---------- BEGIN SOURCE ----------
the behavior is detected on one of our applications. it is hard to say which part of the source code causes the problem. I tried to reproduce it in a smaller application, but it did not occur so far. It actually seems it is caused by a shutdown hook of h2 Database (see the log)....
