Blocked Threads with JNI loop

[Clemens Kühnle]

Thank you very much for the anwser,

I tried it with the Call to Thread.sleep(). Blocking ends!
But there is a Call to a select() statement which is blocking for
1 secound. In this time the other threads are blocked again.
I can change the time that select waits for, but I don't know if this
is the right way, perhaps i'll ask rxtx.

But where is the difference to the sun jvm, is it the threading system?
Or the JNI Implementation?
