LWJGL3 + JavaFX crash on Linux

[piotrp]

Hi,

I have encountered a problem when using LWJGL3 together with JavaFX. Everything seems to work fine unless I open a new dialog.
I am attaching a test case to reproduce the issue. 
In most cases it ends up with the following error:

#  SIGSEGV (0xb) at pc=0x00007fdc59a3ec84, pid=4152, tid=140583549277952
#
# JRE version: Java(TM) SE Runtime Environment (8.0_45-b14) (build 1.8.0_45-b14)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.45-b02 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# C  [libpthread.so.0+0x9c84]  pthread_mutex_lock+0x4


Any ideas how to fix/ work around the issue?

Thanks,
Piotr
