"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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1510009 Title: Java 1.8.0_66 is extremely deadlock prone regarding AWT/GTK interaction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-8/+bug/1510009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
