You've just hit it :-))
I have the logging routine implemented in such a way that it accepts the
messages and prints... well, makes them available to the final logging
device, in the thread runninh with background priority. When I ran this
est, I had to disable all that stuff because the log was becoming silent
after some number of threads (don't remember the exact number, though).
Although, the goal was to test the limits, so I should have had some
sort of logging, otherwise how do I know when it dies? It's possible to
catch the OutOfMemoryError, which I, frankly, expected more than hitting
a thread limit, but I have no clue what would be the system behavior if
JVM wouldn't be able to create the next thread - as far as I understand,
Java language specification doesn't determine the consequences.
