Using the Bug2 application, I’ve reproduced the bug. I haven’t yet identified a root cause. The bug might be related to issue #1120, though the trigger appears to be different.
I ran Bug2 without failure for 18 minutes using a current build of the Minie physics library, so perhaps Minie will provide a workaround. Unfortunately, Bug2 fails on the latest (22-day old, v0.9.3) release of Mine.
I’ll issue a v0.9.4 release of Minie ASAP, so you can try it yourself.
Here it is: Release Minie 0.9.4 · stephengold/Minie · GitHub
If you build with Gradle, here’s a snippet:
repositories {
maven { url 'https://dl.bintray.com/stephengold/jme3utilities' }
jcenter()
}
dependencies {
implementation 'jme3utilities:Minie:0.9.4'
}
