Summary: JDG 6.1.0 : JBMAR-153 - Memory leak in reflection data

Whiteboard:
Fixed In Version: Doc Type: Bug Fix
Doc Text:
Due to the way the JDK creates temporary constructors, and the way the weak references work in the JDK, the weak reference cache will almost always leak constructors over time when, for example, multiple EJB requests are performed to a WildFly server. To solve the issue, the weak ref cache has been eliminated and replaced with a strong reference cache which provides an API to drop a class loader's cache on undeploy. </para> <para> This causes significant performance issues for production applications that encounter this issue.

Setting this bug to verified for Release Notes.

Comment 3 Martin Gencur 2014-03-25 07:32:09 UTC
I doubt this bug should be in release notes for 6.2.1. It's a one-off patch for JDG 6.1. Furthermore, JDG 6.2 already contains the correct version of JBoss Marshalling. So this was already fixed in JDG 6.2.
