> A customer has reported a problem where configuring "double isolation" for web-apps causes problems.
> By "double isolation" I mean JBoss is already configured to provide servlet spec style isolation
> (parent delegation is false), but then the webapp configures it again in jboss-web.xml
> 	<class-loading java2ClassLoadingCompliance="false">
> 		<loader-repository>
> 			xxx:loader=yyy
> 			<loader-repository-config>java2ParentDelegation=false</loader-repository-config>
> 		</loader-repository>
> 	</class-loading>
> This at least causes problems when initializing a servlet context listener, e.g
> with the Spring context listener
