OpenJFX custom build - Java application crash (semi-related to 8262276)

Fri Mar 12 17:54:42 UTC 2021

Arun should be able to help you with the crash you are seeing in debug mode.

Regarding the hang, do you have a test case that will reproduce it? A 
few different developers have reported similar hangs. We ended up 
closing a recently-filed bug, JDK-8260238 [1], because were (and still 
are) unable to reproduce the hang.
