How to fast fail JBoss (ie System.exit()) during container initialization when exception is propagated to ServerImpl.doStart()

Specifically, consider the case where JBoss attempts to open a socket on 1099 during ServiceMBeanSupport (rmi) initialization, but port 1099 is already taken.

Specifically, consider the case where JBoss attempts to open a socket on 1099 during ServiceMBeanSupport (rmi) initialization, but port 1099 is already taken.

Current behavior is that the exception is system.err'd and JBoss continues to initialize. Later, during application runtime, a jndi lookup causes an execution thread to hang -- not good and more difficult to diagnose than a failed container initialization.

So the question is, how to fast fail JBoss on initialization exception?

Here's the trace:

You can't, to my knowledge, but you're right, it is annoying when it does this.

If you're running this on *nix, my suggestion would be to write a bash script which checks for port availability in advance, and only launches JBoss if they're available. Maybe you could do something similar with cygwin on windows.


I also agree that jboss could fail the startup, just as Apache httpd does.

A script to pre-check may not detect that after the check and before JBoss grabs the port another process grabs it. Maybe a rare situation, but possible and also hard to detect.

Since JBoss does not offer to fail when a port cannot be opened, I suggest monitoring the logging. It could be helpful to configure log4j to alert via mail|SNMP|whatever if this situation occurs and propert management could kick in straight away.
