It's been a long while since I've looked at this (in context of JNA
callbacks), but I'm curious why that stack trace would suggest
specifically a not attached thread?  Would it not fail earlier?

A quick search on that trace incidentally found
https://github.com/javafxports/openjdk-jfx/issues/316

On 12.4 specifics, is there anything to be addressed in the release
timescale?  Is this actually a regression on what we had previously?

Thanks,

Neil
