Description
This has been a problem since I started with JavaFX 8 a couple months ago, I just didn't have time to log it yet.  My test app can be found at https://www.dropbox.com/sh/06yoh97jrtu36nj/7prK0vM5Sx

Running through proxy
- Going to Thingiverse WebView throws alot of error mesages and sometimes also NullPointers.  It also can't display many of the images on the website.  In my demo app I didn't add code to download, but in my main app I can download from websites.  Downloading from Thingiverse with proxy enabled causes a timeout
- Can't go to CubeHero.  I can go to CubeHero through Chrome and using the same proxy
- Can't go to YouMagine.  I can go to YouMagine through Chrome and using the same proxy

Not using a proxy
- Still many errors from Thingiverse and many of the images can't display
- Can go to CubeHero
- Can go to YouMagine



Some of the errors that show up with or without proxy.  I haven't been able to produce the NullPointers now
Outstanding resource locks detected:
D3D Vram Pool: 117,793,268 used (43.9%), 117,793,268 managed (43.9%), 268,435,456 total
173 total resources being managed
average resource age is 0.6 frames
0 resources at maximum supported age (0.000000)
74 resources marked permanent (42.800000)
45 resources have had mismatched locks (26.000000)
45 resources locked (26.000000)
101 resources contain interesting data (58.400000)
0 resources disappeared (0.000000)

When these errors come up the images normally do not show up on the web page
Comments
Thanks, Malis, I'll investigate it.

@Anton: As you've probably seen it, I have opened an issue https://javafx-jira.kenai.com/browse/RT-46082 to describe my problem.
27-05-2015
@Malis, RT-34921 is still open because I wasn't able to run the test case as I mentioned in the comments. So, I can't confirm or deny its reproducibility so far. Can you please describe the steps which led you to encounter "locks detected" with 8u60b16? Thanks. @Kobus, thanks for the verification!

I've checked with the given download link jdk-8u60-ea-bin-b16-windows-i586-19_may_2015.exe, but in my case, I still have the error message about Outstanding resource Locks detected: Outstanding resource locks detected: D3D Vram Pool: 12,198,928 used (2.3%), 67,108,864 target (12.5%), 536,870,912 max 11 total resources being managed average resource age is 0.7 frames 0 resources at maximum supported age (0.0%) 3 resources marked permanent (27.3%) 3 resources have had mismatched locks (27.3%) 3 resources locked (27.3%) 5 resources contain interesting data (45.5%) 0 resources disappeared (0.0%) But it seems that this is still an open issue as I have seen that https://javafx-jira.kenai.com/browse/RT-34921 is still marked as "open". Guess I'll have to check the resolution in the other issue then. Thanks for the information!

Just downloaded Java 9 for Windows 64 bit, couldn't configure Netbeans to use it, because it doesn't seem to have the same files/directories as Java 8 or before java version "1.9.0-ea" Java(TM) SE Runtime Environment (build 1.9.0-ea-b65) Java HotSpot(TM) 64-Bit Server VM (build 1.9.0-ea-b65, mixed mode) Running at home so not through a proxy Ran my app with Java 9, but was compiled in 8. java version "1.8.0_45" Java(TM) SE Runtime Environment (build 1.8.0_45-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode) Did a bit of a torture test using thingiverse.com and it worked. It had a hiccup on screen when I was moving quickly forward and back and clicking on things, but 100% better than it used to be. Thank you Now just need to allow reading headers so that I don't need to parse URL's to see where I am :)

I checked that It works fine as well (all the four links in the app) with 8u60b15.
22-05-2015
All existing WebView fixes that are in 9 have already been backported to 8u60. You can download the latest EA build of 8u60 here: https://jdk8.java.net/download.html
22-05-2015
Will this issue be fixed only in JavaFX 9? Is it possible to backport the bugfixes of WebView in JavaFX 8? Because of this issue (among other things), we cannot use WebView in our application, which did not have this problem when we are using JRE 7 and JavaFX 2.2...
22-05-2015
I checked it again with jfx9b53 and I no longer see the reported problems. No "outstanding locks" messages and everything is displayed fine in the App behind proxy (I actually think the latter problem doesn't relate to WebView). Tested it on Windows/Mac. So, I'm closing this.
22-05-2015
On Mac the images are displayed fine w/ and w/o proxy. As to the "outstanding locks" warning, the behaviour is the same. It's reproducible with older jfx versions and is not reproducible with the latest jfx9-dev.
13-03-2015
I reproduced the "resource locks detected" issue with jfx9b37, but I can no longer reproduce it with the latest jfx9-dev. Note that since jfx9 b52 we have an updated WebView (RT-36726). I can't reproduce the NPE as well. What I see is that images indeed are not loaded when I'm navigating to Thingeverse (behind proxy). Though, if I load http://www.thingiverse.com in WebLauncher everything shows fine.

SQE is ok to defer from 8u40 as it is reproducible since 8.
26-11-2014
I think we will need to defer this to 9 given the lack of time and resources.

Due to the gradle switch, and the attended massive changes in the repo structure around that time, this may be difficult / impractical. It might be better to just look at a list of changesets that went in between those two builds.
23-09-2014
Build info is nice but the most important thing is change set. Bisect my son!
23-09-2014
This happened between 8.0-b97 and 8.0-b99
23-09-2014
We are sorry, but at this time we have no resources to work on WebView bugs for the 8u20 release. Unfortunately, we will have to defer them to 8u40.
23-05-2014
Awesomeness. Christmas is coming early for me :) Remember to download my app when you buy my DLP 3D printer :)
26-03-2014
It's currently targeted for 8u20, so if at all possible we will fix it for that release.
26-03-2014
So might this only get fixed in 9? Would put a damper on my app since my app is the only 3D printer control app in the world now with an integrated web browser allowing users to download a 3D object right into a 3D world and print it without ever alt+tabbing
26-03-2014
This is likely the same bug as (or at least closely related to) RT-34443.
