Alexander Schwartz updated JBSEAM-3932:
---------------------------------------

    Description: 
org.jboss.el.util.ReflectionUtil (from jboss-el) uses a  

private static ReferenceCache methodCache

and this ReferenceCache is leaking a thread that is used for cleanup. You can't call a cleanup method from the outside. 

Every redeployment of an application will leak one thread due to this bug. And it causes a memory leak as the web application class loader can't be unloaded due to this bug.

The pom.xml of jboss-el states "JBoss EL is a extended EL implementation, distributed with Seam", therefore I report this bug against Seam.

But the methodCache could be removed from the code as it is not used anyway: it is read in findMethod(), but nothing is stored (the code is commented out in version 1.0_02.CR2, and not present in all other souces (2.0.2.CR1, 2.0.1.GA).

Every redeployment of an application will leak one thread due to this bug. And it causes a memory leak as the web application class loader can't be unloaded due to this bug.
