I will try to generate in a different way, or to inspect the threads

No, because the thread dump doesn't show whether a thread is a daemon
thread or not (which is odd - I thought the standard thread dump did
show that). My guess would be the timer threads. Use one of the many
tools that come with the JDK (or a profiler) to look at the
threads and
see which non-daemon threads are still running.
