             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: ClassLoading
    Affects Versions: JBossAS-4.2.1.GA
            Reporter: Adrian Brock
         Assigned To: Adrian Brock
             Fix For: JBossAS-4.2.2.GA


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
