[Bug 432677] Re: Java JComboBox callback freezes Xorg
IntelliJ IDEA *always* runs on Jetbrains JDK. It's made to run it's own bundled JDK. The JDK can be overridden but it screws with font rendering (purple edges) and possibly other things. The application under debug, however, should *not* run on de Jetbrains JDK. While possible, the Jetbrains themselves discourages it. In project settings you look at the list of installed SDKs and see if the project uses OpenJDK or not. This is the case in my case. It seems indeed that OpenJDK-11.0.4 which I run is affected buy this "fixed in JDK 7" bug 6714678 you linked. They talk about adding a VM argument `-Dsun.awt.disablegrab=true` and this indeeds prevents Xorg from freezing. Simple steps to reproduce (I hope): - sudo apt install openjdk-11-jdk - Download IntelliJ IDEA Community edition, Extract somewhere, run - Create new project (all settings default) - File > Project Structure... > SDKs > Check for or add OpenJDK - Put XLock.java in the src directory - Remove the line `package xlock;` which is now an error - Click next to line number 24 to toggle a breakpoint there - Debug (green cocroach button) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/432677 Title: Java JComboBox callback freezes Xorg To manage notifications about this bug go to: https://bugs.launchpad.net/sun-java/+bug/432677/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Karl-Philipp, Thank you for taking the time to report this bug and helping to make Ubuntu better. However, according to this report, you do not seem to be using Ubuntu's OpenJDK and neither it is the latest version. While it was stated that OpenJDK 11 was used the actual version in the report indicates that JetBrains's VM version 1.8.0_152 was in use. Please try to reproduce it with the most recent version in Ubuntu and let us know if you are still having this issue. Also, please explicitly state the steps that you used to reproduce it and attach - or provide a URL link to - files required for the reproduction (as in XLock.java). Additionally it would be nice to know if you can reproduce it as described in the original bug report in Sun (https://bugs.java.com/bugdatabase/view_bug.do?bug_id=6714678) to be sure we are still dealing with the exact same bug. For now I'm setting its status to Incomplete until that information is provided. You can learn more about bug statuses at http://wiki.ubuntu.com/Bugs/Status.

I know this is quite old, but I still can confirm this bug at Ubuntu 14.04 with current packets installed.

[Bug 432677] Re: Java JComboBox callback freezes Xorg
I've just tested the code attached here with this option Dave told us. It works. Nothing freezes but the application itself. Thus, it's definitely not a bug in Xorg or any driver. The problem is in Java implementation for Linux. http://bugs.sun.com/view_bug.do?bug_id=6714678 I don't agree with their solution though. It's ugly but acceptable to ask a developer to use this option when debugging an application. The problem is that when a buggy application freezes in a combobox callback, it freezes the whole system to the normal user.

@Dave the bug referenced in that thread is similar to this one, but that one was fixed in 6u10.

[Bug 432677] Re: Java JComboBox callback freezes Xorg on Intel and ATI boards
I can confirm this bug on Ubuntu 9,04, 32-Bit. The desktop totally freezes when debugging inside the Java JComboBox-callback in Eclipse. It only affects the ComboBox, debugging a JSlider callback works fine. This happens with Eclipse 3.5 and Eclipse 3.2 (from the Ubuntu repositories). Most important: This does not only happen with an ATI/AMD HD48x0 (fglrx driver, desktop effects disabled) it also occurs with a Nvidia Geforce8400 (nvidia driver, desktop effects enabled).

[Bug 432677] Re: Java JComboBox callback freezes Xorg on Intel and ATI boards
Thanks for the clarification. So whatever action that you perform in the callback (Thread.sleep, big computation, etc.), should be run on the event-dispatching thread. This should freeze the GUI of your application, but definitely not Xorg as a whole. I'm going to mark this as a Xorg bug for now, but it may turn out this is a bug in Java, or maybe even in multiple graphics driver. ** Package changed: ubuntu => xorg (Ubuntu) -- Java JComboBox callback freezes Xorg on Intel and ATI boards https://bugs.launchpad.net/bugs/432677 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
