Ian Springer commented on JBAS-6980:
------------------------------------
It turned out this was happening because the AOP proxy was calling
javassist.CtClass.toClass() which uses the current thread's context classloader to
lookup the class (in this case, org.jboss.aop.instrument.Untransformable). In my case, my
context classloader was not the same classloader as the as5 plugin classloader, which is
the classloader that contains all the JBAS client jars. Setting my context classloader to
the plugin classloader fixed the issue.
Scott, I'm not sure if there's anything you want to do to address this on the PS
side. One possibility would be to call javassist.CtClass.toClass(java.lang.ClassLoader
loader, java.security.ProtectionDomain domain) instead of the no-param version and pass it
the ProfileService class's classloader. If we don't do something like that, then I
think we should at least document the fact that for any threads making remote PS calls,
their context classloader must contain all of the JBAS client jars.
"ClassNotFoundException:
org.jboss.aop.instrument.Untransformable" occurs when
ManagementView.getComponentsForType(<MBean:WebApplication>) is called from a remote
client

Key: JBAS-6980
URL: https://jira.jboss.org/jira/browse/JBAS-6980
Project: JBoss Application Server
Issue Type: Sub-task
Security Level: Public(Everyone can see)
Components: ProfileService
Affects Versions: JBossAS-5.1.0.GA
Reporter: Ian Springer
Assignee: Scott M Stark
Priority: Critical
Note, this occurs even though I have jboss-aop-client.jar, which contains
org.jboss.aop.instrument.Untransformable, in my client's classpath. Here's the
stack trace:
