> When an enum is created it is placed in the static hashmap - cEnumClasses.  
> If the enum is created from a classloader which has a limited lifetime then 
> due to the strong reference the classloader is never garbage collected 
> resulting in a memory leak.  
> I believe that making the cEnumClasses a WeakHashMap should resolve the 
> problem.
