JBoss Hangs When Instantiating Spring Beans
I have an application that currently deploys successfully in Tomcat. I am trying to deploy it in a JBoss 5.1.0.GA container. When I do this, JBoss reads Spring's configuration and tries to pre-instantiate all of the defined singletons.
We see the following line in the log:
INFO [main] support.DefaultListableBeanFactory - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@50f02987: defining beans
JBoss then just hangs. There are no exceptions in the server logs.
The following thread dump seems to indicate a thread is halted with some kind of class loading issue.

Does anyone have any insight?
