[seam-dev] [jboss-as7-dev] help needed with responding to reported classloader leaks in (Rest, Rest WS, JPA, EJB3 activation/passivation, other)...

[Scott Marlow]

I agree that if the user doesn't bundle their own rest east jars, that 
would probably work around the issue.

I haven't seen any standalone tests that recreate the leak yet but it 
looks likely that the application copy of ResteasyBootstrap.java 
(http://anonsvn.jboss.org/repos/seam/branches/community/Seam_2_2/src/resteasy/org/jboss/seam/resteasy/ResteasyBootstrap.java) 
would call the API 
ResteasyProviderFactory.setInstance(ResteasyProviderFactory factory) 
which would save the static reference that doesn't get cleared.  Worse 
than that, I think the setInstance call would blow away any other 
ResteasyProviderFactory instance that is already set.

Which backs up the assertion that rest easy jars shouldn't be bundled 
with a user app currently.  ResteasyBootstrap should probably clear the 
instance at shutdown time but that wouldn't change the API static issue.
