I am afraid it's some threading issue that depends on timing (such as
timedwait). It's interesting to know how RI behaves with those test
cases.

No, my process load CPU only. I run it as: java -cp . Stress
---------------- Stress.java ---------------------------
public class Stress {
public static void main(String[] args) {
Run[] threads = new Run[4];
for (int i = 0; i < threads.length; i++) {
threads[i] = new Run();
threads[i].start();
}
while (true){}
}
}
class Run extends Thread {
public void run() {
long i = 0;
try {
while (true) { i++; }
} catch (Exception e) {
System.out.println("Exception:" + e);
}
}
}
