> 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.
