Description

J2SE Version (please include all output from java -version flag):
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)


Does this problem occur on J2SE 7ux, 8ux?  Yes / No (pick one)
Unknown


Operating System Configuration Information (be specific):
OSX 10.9.3


Hardware Configuration Information (be specific):
IMac 24'' early 2009


Bug Description:
On open a popup window sporadic a 100% CPU occur and the GUI is not
responding. Details see in the follow Thread dump.
It look like that the thread "AWT-EventQueue-2" is polling on the native
thread "AWT-AppKit" which block from the "AWT-EventQueue-2"

The cause of the problem seems that the thread "AWT-AppKit" is accessing
the Swing GUI which is not valid. This seems a design mistake.

Quite a serious issue. No workaround. But not a stopper. Too late for PIT unfortunately. Any way, SQE OK to have it in CPU14_04 GAC build.

it might be consider to fix in 8u once we have fix done in 9

1. Window.isFocusableWindow() method can be @Overridden by user code. Under normal circumstances, AWT should never call such methods directly from the toolkit thread. That is the reason there are various _NoClientCode() methods (e.g Component.getFont_NoClientCode(), etc.) The stack trace from the Description of this issue suggests that we violate this rule in LWAWT. And this needs fixing. 2. Using a nested event loop sounds like a viable solution, and it would automatically resolve the _NoClientCode() issue btw because we would no longer call this method from AppKit directly. But I agree it isn't a low-risk solution. 3. I doubt it is a good idea to leave this bug unfixed for 8u20. This is an important update release containing lots of fixes for problems that were left unresolved in 8 GA. Also, so far as I know, IDEA is one of the most popular Java IDEs in the world (note, myself, I don't use this IDE, so I'm not an interested party here). If developers can't run IDEA with 8u20, this looks bad to me. However, I agree that we need to assess all the risks before proposing the fix for 8u20.
26-06-2014
To fix this particular issue we have several options: 1. Open a nested loop and go to EDT synchronously. 2. Try to cache the isFocusable on peer level somehow. Anthony, I actually did not understand your _NoClientCode() suggestion. What do you mean exactly? I think we cannot fix it for 8u20. It's in a very late release stage now, and all the solutions I can imagine are pretty risky. This is only a part of a bigger issue. Recently I've made a javaagent that instruments loaded classes to check for illegal AppKit thread access. Running only a little part of our regression test suite with my tool I found lots and lots of potential deadlocks and methods illegally called on Appkit. So we were thinking if it's possible to provide something more general that point fixes for each deadlock.
26-06-2014
This looks like a pretty serious issue to me. Also note that JetBrains have just reported that IDEA dead-locks because of this bug when running with 8u20b19. I suggest to increase the priority to P2 and try to fix this issue for 8u20. On a side note, it looks pretty insane that Window.isFocusableWindow() involves a sort operation, but that seems to be a separate issue. The real problem is that this method is called directly from the AppKit thread. This begs for some _NoClientCode() solution (not sure if this is going to help directly, but this is still a necessary part of the fix), or caching the value in the peer, or doing something else.
26-06-2014
requires back port
26-06-2014
That's another example of a problem we can get if we call target methods directly.
