Pete Muir reassigned WELD-570:
------------------------------
Assignee: Roger Kitain
> Partial export of javasisst from Weld breaks other javasisst clients
> --------------------------------------------------------------------
>
> Key: WELD-570
> URL: https://jira.jboss.org/browse/WELD-570
> Project: Weld
> Issue Type: Bug
> Components: OSGi support
> Affects Versions: 1.1.0.BETA1
> Reporter: Harald Wellmann
> Assignee: Roger Kitain
>
> weld-osgi-bundle.jar (as used in Glassfish 3.0 and higher) still contains a
> buggy version of javasisst causing memory leaks.
> See WELD-453 and JASSIST-104. Even though Weld itself no longer uses the
> problematic javassist ProxyFactory, it is still the root cause for a memory
> leak occurring when HIbernate (or potentially any other Javassist client) is
> used on Glassfish.
> The problem exists in Glassfish 3.0.1 and also in the promoted build 3.1-b12
> using a 1.1.0 prerelease of Weld, see
> https://glassfish.dev.java.net/issues/show_bug.cgi?id=12368
> weld-osgi-bundle.jar contains a version of javassist which is almost but not
> fully private. There is a package export for javassist.util.proxy. When
> deploying a WAR on Glassfish containing Hibernate (3.5.3) and another copy of
> Javasisst required by Hibernate, then by parent classloader delegation
> Hibernate will end up using the javassist ProxyFactory from Weld, registering
> its proxies deep down in the container, and thus causing a memory leak with
> each redeployment of the WAR.
> Weld should either keep its included version of javassist fully private or
> import all of javasisst via Import-Package, relying on javasisst installed in
> a separate bundle.
