[Hibernate-issues] [Hibernate-JIRA] Updated: (HHH-1236) Remove static reference to classloader, to avoid memory leak at webapp reload

[Steve E. (JIRA) <no...@at...>]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1236?page=all ]

Steve Ebersole updated HHH-1236:
--------------------------------

    Fix Version: 3.1.3
                 3.2.0.alpha1

While it may not be a bug, it does in fact contribute to the inability of the classloader to get cleanly released.  And there is no need for it.  There is absolutely no code in Hibernate that actually uses that overloaded DTDEntityResolver constructor, thus there is really no reason at all to even keep a ref to the classloader
