I am using ubuntu 18.04 in docker environment and running swtbot tests using eclipse. I get the same error. I updated my docker file to install libx11-6 but the problem still exists. The tests execution is aborted with the following error message
[xcb] Unknown sequence number while processing queue [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that. java: ../../src/xcb_io.c:259: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed. Is there any fix/workaround available for this bug? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782984 Title: Assertion `!xcb_xlib_threads_sequence_lost' failed with multiple applications To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libx11/+bug/1782984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
