I've done a bit of a google search on this problem and it seems to be a 
somewhat confused situation. I've seen reports of 8 not working, but 
falling back to 8 as fixing it. I've seen 11.0.5 is broken but 11.0.4 
works, but someone else said 11.0.4 was fine. I've followed other 
reports that indicate this all relates to a glibc bug.

but also suggests a different solution:

"you either need openJDK 11.0.4 (not 11.0.5) or lwjgl3 instead of lwjgl2 

 From what I can tell from the reports that I have found is that the 
problem seems to come and go with OpenJDK builds from different OpenJDK 
distributors. I did not see any reports that conclusively indicated the 
problem was seen on Oracle JDK. My suspicion is that whether or not this 
problem appears depends on how the JDK was built i.e. which version of 
glibc it has been linked against. The Oracle JDK binaries for 11.0.4 and 
11.0.5 seems to have the exact same build environment. I can't comment 
on any binaries from other places e.g. AdoptOpenJDK. This conclusion was 
also proposed on the jmonkeyengine post above:

"If they’re right, it’s going to depend on what version of glibc you jvm 
is using, and possibly what was present when your native payload was 

Not sure what can be done at the OpenJDK end.
