    Fix Version: 2.2

> Use of enum prevents a classloader from being garbage collected resuling in out of memory exceptions.
> -----------------------------------------------------------------------------------------------------
>
>          Key: LANG-262
>          URL: http://issues.apache.org/jira/browse/LANG-262
>      Project: Commons Lang
>         Type: Bug

>  Environment: All
>     Reporter: Neil Redway
>     Priority: Critical
>      Fix For: 2.2

>
> 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.
