Subject [jira] Created: (LANG-262) Use of enum prevents a classloader from being garbage collected resuling in out of memory exceptions.
Date Mon, 05 Jun 2006 08:40:30 GMT
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


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.
