Potential class loader leak caused by the thread local in
org.apache.axiom.util.UIDGenerator
--------------------------------------------------------------------------------------------
Key: AXIOM-354
URL: https://issues.apache.org/jira/browse/AXIOM-354
Project: Axiom
Issue Type: Bug
Components: API
Affects Versions: 1.2.10
Reporter: Andreas Veithen
UIDGenerator uses a ThreadLocal with a value class that belongs to Axiom
(namely UIDGeneratorImpl). Since the ThreadLocal is never cleaned up explicitly
(doing that would break the UIDGenerator), this may cause a class loader leak
(i.e. in a Web application, it may prevent the class loader from being garbage
collected when the application is stopped). Since UIDGeneratorImpl basically
stores 3 values of type long, it should be easy to refactor the code so that
the value class ThreadLocal is not loaded from the application class loader
(e.g. by using long[] as value class). However, I first need to confirm that
there is really a class loader leak here.
