If the run() method of a thread
terminates due to an uncaught exception, then by default, this thread
will die and the stack trace of this exception will be printed to
System.err.
This default behaviour is not satisfactory. At first, we would like to see the exception message chain, too. And secondly, we would really like to see it in the application's user interface, instead of in a may-be suppressed console output.
