<div class="jive-rendered-content"><p>I put some breakpoints in RegisterModuleCallback.addModule(), JBossClDelegatingClassPool constructor, and in JavassistTypeInfoFactoryImpl.delegateToIntrospectionImplementation() (where failed ClassPool lookups end up) and it seems that there is a problem in that the aop classloader does not get registered with the classpools. The flow of these break points is:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><div id="_mcePaste"><ol><li>RegisterModuleCallback.addModule() - bootstrap-classloader:0.0.0</li><li>RegisterModuleCallback.addModule() - jmx-classloader:0.0.0</li><li>JBossClDelegatingClassPool() - bootstrap-classloader:0.0.0</li><li>JBossClDelegatingClassPool() - jmx-classloader:0.0.0</li><li>Get TypeInfo for AspectManagerJMXRegistrar fails (aop classpool not created yet)</li><li>RegisterModuleCallback.addModule() - deployers-classloader:0.0.0</li><li>JBossClDelegatingClassPool() - deployers-classloader:0.0.0</li><li>Get TypeInfo for AOPAnnotationMetaDataParserDeployer fails (aop classpool not created)</li><li>Get TypeInfo for AOPDeploymentAopMetaDataDeployer fails (aop classpool not created)</li><li>Get TypeInfo for BeansDeploymentAopMetaDataDeployer fails (aop classpool not created)</li><li>RegisterModuleCallback.addModule() - profile-classloader:0.0.0</li><li>JBossClDelegatingClassPool() profile-classloader:0.0.0</li></ol></div><div id="_mcePaste"> </div><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Looking at the sequence of files from bootstrap.xml:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><ul><li>bootstrap/vfs.xml  - No classloader</li><li>bootstrap/classloader.xml - defines bootstap-classloader:0.0.0</li><li>bootstrap/stdio.xml - defines stdio-classloader:0.0.0</li><li>bootstrap/kernel.xml - defines asynch-classloader:0.0.0</li><li>bootstrap/aop.xml - defines aop-classloader:0.0.0 and the RegisterModuleCallback</li><li>bootstrap/jmx.xml - defines jmx-classloader:0.0.0</li><li>bootstrap/deployers.xml - defines deployers-classloader:0.0.0</li><li>bootstrap/profile.xml - defines deployers-classloader:0.0.0</li></ul><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Assuming these get deployed in order (which I will look at next) it seems strange that the RegisterModuleCallback receives bootstrap-, jmx-, deployers- and profile-classloader, but not the aop-, stdio and, asynch-classloaders</p></div>
