Hi,

I'm quite sure you are not the only person who ever used H2 in OSGi :-)
FilePath is old.

In my experience Java threads don't "just stop" :-) I'm quite sure it's a
runtime exception you didn't catch. (In theory the thread might be blocked
or wait, but I doubt it)
What I would do is add "try { .. } catch (Throwable e) {
e.printStackTrace(); }". If that doesn't help, I would debug it.

Thomas
