[Wrapper-user] Re: my wrapper stoped and i don't know why

[Leif M. <le...@ta...>]

Ralf,
The wrapper is designed to exit cleanly when all non-daemon threads have
quit.
Most likely, your application is launching one or more threads with
their daemon
flag set and then all other threads are exiting.

Daemon threads are designed to be running in the background until the JVM is
ready to shut down. They are designed so that your application does not need
to worry about shutting them all down before the JVM will exit. The
Swing event
handler thread is an example of a daemon thread.

Running java without the wrapper should behave in the same way. That is what
the following line is telling you.

jvm 1    | All non-daemon threads have stopped.  Exiting.


Is this an application you wrote yourself? How does it behave when not using
the Wrapper?
