[jboss-jira] [JBoss JIRA] Commented: (JBAS-5022) WebAppClassLoader is not optimized for RMI

[Adrian Brock (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBAS-5022?page=comments#action_12412599 ] 
            
Adrian Brock commented on JBAS-5022:
------------------------------------

The Ant Compiler and URLs in general cannot work with the new classloader.
We have to use the Eclipse compiler which properly understands the classloading rules.

e.g. things a list of urls doesn't give you:
* filtered packages
* OSGi style imports and uses constraints from other deployments
* AOP enhanced classes
etc.

Having said that we should probably look at fixing this once and for all in the 
JBossRMIClassLoader::getClassAnnotation()
rather having each classloader hack its own solution (which may not always be possible?)

> The WebAppClassLoader used by web applications to scope classes does not override
> getURLs() to return new URL[0]
> This means that if a webapp makes an RMI request using a class from inside the web app,
> all the WEB-INF/lib and WEB-INF/classes urls are sent across the wire as class annotations.
