[jira] Commented: (AXIS-2284) thread hangs on org.apache.axis.utils.JavaUtils.isEnumClass

    [ http://issues.apache.org/jira/browse/AXIS-2284?page=comments#action_12356807 ] 

Davanum Srinivas commented on AXIS-2284:
----------------------------------------

Frank,

looking at isEnumClass(), could you please try to switch the key of the hashmap to the full package + class name instead of the class itself? i know if different classloaders are involved it is dicey, but we are looking for the same info so it should be ok. Please try it and let us know.

thanks,
dims
