"atk-wrapper went through some quite big updates between 15.04 and 15.10, so I'd be betting on that being the issue (or it somehow triggering a Java edge case)"
I don't think that is the primary bug. Bugs in Debian and Redhat are much older and look like perfect match to this bug. It feels like a race condition somewhere but I don't know how to debug jvm. Maybe some kind of trace from xcb telling which threads are using which connection would help. -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-8 in Ubuntu. https://bugs.launchpad.net/bugs/1510009 Title: Java 1.8.0_66 is extremely deadlock prone regarding AWT/GTK interaction Status in openjdk-8 package in Ubuntu: Confirmed Bug description: Since upgrading to Ubuntu 15.10 from Ubuntu 15.04, the various GUI applications that I run, including Netbeans and Minecraft have been suffering from dead/waitlocks which prevent them from operating properly. Since I have reproduced this issue these two completely different codebases, I am moving the bug further upstream. The original Netbeans bug report can be viewed here: https://netbeans.org/bugzilla/show_bug.cgi?id=256124 Essentially, during routine interaction and calling of various AWT methods, somewhere between 8u45 (15.04) and 8u66 (15.10), something broke causing the application to hang intermittently when these methods are called. Some sample jstack traces are attached, the issue should be fairly obvious to spot.
