JVM shudown behavior

[rakcheru]

Greetings,

(JBoss version : 4.2.3)

For the past few days i am stuck with finding any documentation for JVM shutdown behavior for JBoss. I am trying to understand whether the "shutdown.sh" will allow any user threads (non-daemon threads) to complete before shutting down JVM.

From the findings looks like JVM shutdown terminates non-daemon threads and does NOT wait for them to complete. Is this behavior configurable ? Can anybody please clarify this or point me to any documentation ?

Thanks much in advance,

Rakesh

The shutdown.sh script try to bring the server controlled out of work, e.g. remove from cluster, finish all transactions and so on.

The script sends only a request to JBoss core that the server should be stopped (can also be done by kill -1).

The script does not work in different circumstances (e.g. massive GC).

If you want to stop the JVM immediately you might use 'kill -9' but this may affect db connections.
