[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4317) Memory leak in EnumType class.

[Pablo Saavedra (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=35304#action_35304 ] 

Pablo Saavedra commented on HHH-4317:
-------------------------------------

Ondrej, your workaround is fine but it won't work on JBoss, since it includes the hibernate jar in it's lib directory. In that case, adding hibernate jar to the war will probably result in classloading issues.

BTW, does this cache actually yield a significant performance gain?

> Holding enum values in static enumValues map in EnumType class causes memory leaks on application server where hibernate is loaded by application server's common classloader (like for default configuration of JBoss4).
> SoftReference or SessionFactory based caching should be used instead.
