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. Thanks in advance. ** Changed in: openjdk-6 (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-6 in Ubuntu. https://bugs.launchpad.net/bugs/432677 Title: Java JComboBox callback freezes Xorg Status in Sun Java: New Status in openjdk-6 package in Ubuntu: Incomplete Bug description: My machine is a desktop with an Intel Core 2 Quad, 2Gb and a video board Intel(R) 965G. I am using Ubuntu 9.04 32 bits, Eclipse 3.5 (Galileo), Sun Java 1.6.0_16 provided by sun-java6-* packages. Steps to reproduce (please read it until the end before trying): * Create a Java project in Eclipse. * Add the attached XLock Java class in this project * Put a breakpoint in the method actionPerformed() * Run this class (note that it has a method main()) in debug mode * A tiny window will appear * Select another animal in the combo box * Eclipse should stop in the breakpoint * All your Xorg is locked now. You can move your mouse, but nothing responds any more * To unlock it press CONTROL+ALT+F1, login to the terminal and kill the latest Java process * Everything gets back to normal I don't know exactly where the problem is, but Xorg should never lock because of a problem in an application.
