Closing the last tab in Dayflower Application causes a hang

[madhephaestus]

The Application hangs and keeps the mouse bound. I was able to kill it from the command line and got the following exception

Could this perhaps be the bug? https://bugs.openjdk.org/browse/JDK-8148377?attachmentOrder=desc

What version of Java are you using? Are you able to reproduce the bug and, if that is the case, how did you do it? I havn't been able to reproduce it myself.
