Hello Luigi,
here are some call stacks i managed to get.
I ran the program several times and attached the Visual Studio debugger to
the Java process.
I had tried manual calls to the Java garbage collector before, to see if
they might solve the problem, which they didn't.
But the sets of possible call stacks seem to differ, depending on whether
the gc was run manually or not,
though it could also be, that i just didn't try often enough.
One of these call stacks were presented when the program got the "pure
virtual function call" error:
With the Java garbage collection run manually before each swap evaluation:
