I am trying to get a web app working on jboss 5.0.1.
It works fine with jboss 4.2.2.
I have fixed some issues with deployment descriptors, and as it would fail if the war file contained its own xercesImpl.jar (2.9.0) inside WEB-INF/lib, I removed that along with xml-apis and xmlParserAPIs.

Now the entire jboss server appears to hang when trying to initialize the app.
It uses lots of memory and CPU, gives no reponse on port 8080 and nothing in server.log. Have to kill the java process to stop it.

Starting jboss with debugger attached, I get the following exception:

The org.apache.cocoon.servlet.* stuff is initialization code inside my app framework, preparing for reading configuration from xml.

The line:

at org.apache.avalon.framework.configuration.DefaultConfigurationBuilder.getHandler(DefaultConfigurationBuilder.java:145)

appears to refer to the following line of code:

if( m_parser.getFeature( "http://xml.org/sax/features/namespaces" ) )

This is all on Windows, jdk1.5.0_14.
JAVA_OPTS:

-Dprogram.name=run.bat -server -Xms1024m -Xmx1024m -XX:MaxPermSize=128m -XX:+HeapDumpOnOutOfMemoryError -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y

Can anyone see what might be the problem here?
