When it happens, it seems to be always reproducible. I tried another
Java program that uses JNI which came to my mind (besides arduino),
namely Vuze (used to be Azureus), and that crashes too, so I suspect
from this very small sample that many Java programs that use JNI do
crash. However a very simple JNI test program does not crash.

Yes, they seem to fix it.
