Description

This is potentially reproducible with any Swing/JFXPanel app. I reproduce it in IDEA + Markdown plugin [1]

Steps:

1. Activate VoiceOver (Cmd+F5)
2. Run IDEA w/ Markdown plugin
3. Open any *.md file with JavaFX WebView as the viewer

It deadlocks [2]

Another way to reproduce:

1. Run IDEA w/ Markdown plugin
2. Open any *.md file with JavaFX WebView as the viewer
3. "In parallel" with the 2nd step nevigate intensively across the IDEA system menu. 

It deadlocks [3]

I tested the 8u backport and there are no issues with our testing environment. This is approved to push to FX 8u-dev for 8u.152
15-06-2017
Raising priority to P2 since this is a deadlock in a reasonably common startup case without a good application-level workaround.
15-06-2017
We will need to figure out how to deal with the fact that the boot JDK we use to build / test FX will not necessarily have the fix for JDK-6980209. Ideally there would be a way we could check at runtime whether the JDK we are running with has the fix for JDK-6980209 without explicitly checking a version number. If this is not possible we will need another solution.
18-02-2017
Kevin, the backport version is http://cr.openjdk.java.net/~ssadetsky/8172554/8u/webrev.00/. But before we need to backport JDK-6980209 as well.
15-02-2017
The problem you mentioned would only happen if someone were to try to concurrently create a JFXPanel on two threads, a background thread and the EDT. As we discussed in earlier comments, I would consider that an application bug (it seems unlikely that an application would make this mistake, though). An application that just uses "new JFXPanel()" on an arbitrary thread as a way to initialize FX will continue to work just fine with no problems regardless of the thread on which it is called.
06-02-2017
I will push this shortly. Given the nature of this bug, we will consider a backport to JDK 8. Semyon: Can you please prepare a webrev against 8u-dev and post a backport request?
06-02-2017
Ok, Kevin, I will prepare the backport patch. One extra comment. initFX() method is synchronized, if non-EDT thread enters into it and starts the platform it may block the EDT thread if another JFXPanel is created on it. I would recommend to construct JFXPanel on EDT only as any other Swing component.

06-02-2017
Thank you for review, Kevin. The next webrev includes all your points: http://cr.openjdk.java.net/~ssadetsky/8172554/webrev.04/
06-02-2017
Oddly enough, just adding the null check in teardown is sufficient to fix the failure, even if you leave the call as: if (frame != null) { SwingUtilities.invokeLater(frame::dispose); } [additional info] Maybe not so odd after all. With the existing code, the NPE is thrown in the test thread to the caller of teardown (JUnit) whereas with frame.dispose() moved inside a lambda that is passed to invokeLater, the NPE is thrown in the EDT and not propagated to the test thread. Anyway, the solution is the null check as shown above.
04-02-2017
I did a little more debugging, and I found that the teardown method is being called even though the "assumeTrue" fails, which I guess makes sense if you think about it. Given this, you should add a null check for frame in teardown (which is good practice anyway). Two more comments on the test and then I think it will be ready: 4. You have a whole lot of extra spaces between the name of the test and the opening curly brace. 5. Since you rely on the initial value of 'stop' I think it will be clearer to explicitly initialize it to 'false' in the declaration (and I don't think there is any need to set it at all in the teardown method).
04-02-2017
I have no idea why this would be the case, but if you replace the following in your teardown method: SwingUtilities.invokeLater(frame::dispose); with this: SwingUtilities.invokeLater(() -> frame.dispose()); then the assumeTrue in the setup method works. I suspect this is a bug in JUnit or gradle.
04-02-2017
One more issue. I ran this on Linux and it doesn't look like the assumeTrue is working properly in the @BeforeClass method: test.javafx.embed.swing.FXPanelTest > classMethod FAILED org.junit.internal.AssumptionViolatedException: got: <false>, expected: is <true> at org.junit.Assume.assumeThat(Assume.java:70) at org.junit.Assume.assumeTrue(Assume.java:39) at test.javafx.embed.swing.FXPanelTest.init(FXPanelTest.java:63) test.javafx.embed.swing.FXPanelTest > classMethod FAILED java.lang.NullPointerException at java.base/java.util.Objects.requireNonNull(Objects.java:221) at test.javafx.embed.swing.FXPanelTest.teardown(FXPanelTest.java:110)
04-02-2017
Actually, never mind about adding a second test for JFXPanel constructed off thread. We already have a launcher test that verifies we can still call "new JFXPanel()" on an arbitrary thread. That test still passes with your fix, so no problems there. The fix itself is fine. I have three comments on the test: 1. Please move it under test/robot so that it only runs with the "USE_ROBOT" property is set to true. 2. As mentioned above, I think JFXPanelTest would be a better name for the test class. 3. We try to avoid wildcard imports in our code, so could you expand the swing and awt imports? Thanks.
04-02-2017
No, I didn't mean to test the concurrent case. I was just thinking of a second test similar to your test case, but with the JFXPanel being constructed outside of SwingUtilities.invokeLater. Oh, and I would change the name from FXPanelTest to JFXPanelTest since the name of the class is JFXPanel.
03-02-2017
Do you mean add system test scenario where the JFXPanels are created concurrently? Or you mean some sort of unit testing for the JFXPanel constructor?
03-02-2017
Oh, right I see the test. The code change looks fine now. I will test it out. It would be good to have a second unit test that calls "new JFXPanel()" from the test thread to check the other path. I'll review in parallel.
03-02-2017
http://cr.openjdk.java.net/~ssadetsky/8172554/webrev.03/ Test was always in the fix.
03-02-2017
It might be better to move all of the new logic into initFX (which is synchronized, so you wouldn't need an atomic boolean), check whether it is already initialized, then if not, check whether it is on the EDT. Something like this, maybe? initFx() { if (fxInitialized) { runLater(() -> {}); // Note that this is probably not needed, but matches current behavior return; } if (on the EDT thread) { spin up a nested even loop to call platform startup } else { just call platform startup } fxInitialized = true } Also, we ought to consider adding unit tests (system tests) for this.
03-02-2017
Actually, that's a very good point about the secondary loop not being needed on the non-EDT thread. The question, though, is whether it would be harmful? As for multiple apps on the same JVM that isn't supported.
03-02-2017
But secondary loop is not needed on non-EDT thread, is it? What if user concurrently starts two apps on the same JVM: 1- FX app with FX init on main thread. 2. - Swing app that uses JFXPanel. Is that usage prohibited?
03-02-2017
>> concurrent calls to "new JFXPanel()" including the case of one on the EDT and one off the EDT this means a mistake in user code. I would better do not run FX initialization if "new JFXPanel()" is not called on EDT. This will protect us from the concurent initialization as well as from starting the secondary loop on non-EDT thread. But you didn't answer my first question, which was: >> But what if the Platform.startup() is run on non-EDT thread concurrently with JFXPanel construction on EDT? The latter seems much more probable because FX >> may be initialized explicitly in the user code and it may be called on any thread according to the spec.
03-02-2017
It will be a regression in behavior if you prohibit calling "new JFXPanel()" from off the EDT. Many JDK 8 applications use this (at our suggestion) as a way to initialize JavaFX since we have no public API. As to your other question, that would be an application bug: the only time an application should use Platform.startup is if they are not using one of the other means to start the FX platform (Application.launch, new JFXPanel, or new FXCanvas). I do agree that two concurrent calls to "new JFXPanel" could also be considered an application bug. However, I'm not sure that invalidates the suggestion to using the "is initialized" check. It seems clearer and allows for the cleanup of using the public Platform.startup instead of the non-public PlatformImpl.startup. Is there another reason to avoid doing it this way?
03-02-2017
You placed the fxInitialized boolean into JFXPanel. That can prevent initFx() from running concurrently if two JFXPanel panels are constructed at the same time on different threads, although, which unlikely happens in case of correctly written user code. But what if the Platform.startup() is run on non-EDT thread concurrently with JFXPanel construction on EDT? The latter seems much more probable because FX may be initialized explicitly in the user code and it may be called on any thread according to the spec. As for the exception. Not sure that catching an error makes sense because java may not recover after error. Anyway. Whether the following code is acceptable for you? ... secondaryLoop.enter(); if (th[0] instanceof RuntimeException) { throw (RuntimeException)th[0]; } else if (th[0] instanceof Error) { throw (Error)th[0]; } else if (th[0] != null) { throw new RuntimeException("FX initialize error", th[0]); }
02-02-2017
One more thing I noticed is that you catch and forward Exception but not Error from the thread that calls initFX. If you catch Throwable (or separately catch RuntimeException and Error) then you will be able to handle those as well.
02-02-2017
I guess I didn't explain well (and I was really mixing two things with my suggestion about using the public API). What I meant is that you could do something like the following, which would avoid the try/catch and be a bit cleaner (and is thread-safe, although apps shouldn't create a JFXPanel on a non-EDT thread anyway, much less create two of them concurrently on two different threads). private static final AtomicBoolean fxInitialized = new AtomicBoolean(false); public JFXPanel() { if (fxInitialized.getAndSet(true)) { // already initialized Platform.runLater(() -> {}); } else { // put the nested loop code / call to initFX here } } Separately, once you do that, there is an opportunity to use the public API for Platform.startup in place of the internal PlatformImpl.startup method. The only difference between those two methods is that the public method will throw an exception if you call it more than once. When we added the public method, I had considered going back to JFXPanel and making exactly this change, but it wasn't (and still isn't) that big of a deal. So this part of my suggestion is really just a little bit of nice cleanup to remove one more occurrence of calling an internal methods. This change really isn't important and probably led to the confusion.
02-02-2017
Yes, the AtomicBoolean will correctly handle two concurrent calls to "new JFXPanel()" including the case of one on the EDT and one off the EDT, so that's another reason for it being a good pattern. As for your second question, the above code to rethrow Error looks fine and matches what the FX Application launcher code (in LauncherImpl) does.
02-02-2017
Kevin, in which scope the atomic boolean could be created? FX initialization may be run not only from JFXPanel constructor. Please, clarify. Also, I see no benefits in replacing the finally{} block with runnable argument of the Platform.startup(). The final block seems much clearer.
01-02-2017
If we really can rely on the correct behavior of SecondaryLoop.exit being call before .enter, then that part of the fix is OK, but we should file a spec bug against AWT to clarify that so we aren't relying on undocumented behavior. I would like to do some testing to make sure that there are no issues with the context classloader or when running with a security manager. Also, since change affects all platforms, we need to run the tests on all of them. Also, it seems cleaner to use an atomic boolean for initialization so you don't have to do a try/catch -- that way there is no chance that two threads could each create a secondary loop. Oh, and if you do make this change to ensure that platform startup is only called once, you can use the public API: Platform.startup (not really important, though).

We can rely on SecondaryLoop concurrent calls. JDK9 SecondaryLoop implementation is a thread safe and it is well tested. See JDK-6980209.
27-01-2017
1. I had the same question that Jim raised. It turns out to work when calling them out of order, and looking at the implementation I can see why it works, but I don��t think we should rely on unspecified behavior like this. You might try Jim��s suggestion. 2. initFx() ends up being a no-op when called more than once. It's fast enough that we don't care currently. Now that you are planning to spin up a secondary event loop you should only do the initialization once (the first JFXPanel that is constructed) so it won��t be a performance hit. 3. You need a try/catch/finally call around initFx, otherwise if an exception or error happens you will hang waiting for the secondary loop to exit. In the case of an exception or error you will need to capture it and rethrow it to the caller of the constructor.
27-01-2017
What stops the thread from running and triggering the secondaryLoop.exit() before the outer thread calls secondaryLoop.start()? Can they be called out of order? If this is really an issue then the start() on the new thread could be posted as an event so that the secondary thread is already running when it happens.
26-01-2017
Fixed the component to be javafx since it is not a bug in swing itself.
26-01-2017
I would like to propose a simple solution, do not block EDT while JFX is initialized: http://cr.openjdk.java.net/~ssadetsky/8172554/webrev.01/
26-01-2017
Yes, I applied the patch to GlassApplication.m. Seems the JavaRunLoopMode is not that magic as I thought. If you look at LWCToolkit.m, Java_sun_lwawt_macosx_LWCToolkit_doAWTRunLoopImpl, you'll see the processEvents flag. JNFRunLoop selectors can't be dispatched without explicit dequeuing of the related event (nextEventMatchingMask). So, it doesn't help w/o enabling the RunLoop to process events. Actually, I have a working solution for the problem, but I hoped there could be a simpler one. You can see it here: https://github.com/JetBrains/jdk8u_jdk/commit/a9dbb6990fac0c659297487a261ba9170e5fb3ad SunToolkit.unsafeNonblockingExecute(Runnable) is used in IDEA to wrap JFX-critical invocations prone to deadlock on OSX. The fix seems quite a hacky to me (that's why I hadn't proposed it) but you can probably make something better out of it. Or you can suggest an alternative solution. The evil, actually, comes from the fact that a11y & menu handling code use invokeAndWait on EDT. Changing this logic is not an easy thing to do though...
17-01-2017
By the way did you modify the patch when applying it to 8? MacApplication.m was renamed to GlassApplication.m in 9.
16-01-2017
I made FX to run in javaRunLoopMode as you proposed. Do you have any ideas why it did not work? I can also deadlock Ensemble8/SwingInterop on 9 by clicking its JTable cells quickly.
16-01-2017
Semyon, unfortunately, the suggested fix didn't work for me in jdk8 + IDEA + markdown. It deadlocks the same way.
16-01-2017
I didn't try to reproduce it in jdk9, but as the related logic hasn't changed I suppose the problem still exists. Semyon, thanks for the fix, I'll try it and will let you know the results.
13-01-2017
http://cr.openjdk.java.net/~ssadetsky/8172554/webrev.00/ Anton, can you confirm that the fix works for you?
13-01-2017
Ok
12-01-2017
Victor, I think what Anton means makes sense. Possible, I cannot reproduce the issue in 9 because its probability is very low. Switching Glass toolkit to JNFRunLoop will add FX dependency on JavaNativeFoundation SDK. If there will no objections we can do this.
12-01-2017

12-01-2017
I made a simple Swing app using JFXPanel with WebView. Activating VoiceOver works well except it doesn't read the WebView content only swing controls text is read. Anton, it would be nice to get instructions how to reproduce this issue in 9. --------- public class FXPanelTest { static WebEngine webEngine; static void load() { Platform.runLater(() -> { webEngine.loadContent("<html><head></head><body><h1>Test</h1>test</body></html>"); }); } public static void main(String[] args) { SwingUtilities.invokeLater(() -> initSwing()); } static void initSwing() { JFrame frame = new JFrame("FX"); frame.setSize(600, 600); final JFXPanel fxPanel = new JFXPanel(); Button load = new Button("Load"); frame.getContentPane().add(load, BorderLayout.SOUTH); load.addActionListener((e) -> load()); frame.getContentPane().add(fxPanel); frame.setVisible(true); Platform.runLater(() -> initFX(fxPanel)); } private static void initFX(JFXPanel fxPanel) { WebView myWebView = new WebView(); webEngine = myWebView.getEngine(); Scene scene = new Scene(myWebView); fxPanel.setScene(scene); } }
12-01-2017
The issue is reproducible on JDK 8. Testing on JDK 9 is not possible. Intellij Idea is not compatible with JDK9.
