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

[Ondrej Medek (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4317?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ondrej Medek updated HHH-4317:
------------------------------

    Attachment: EnumType.java

An EnumType withut caching, suitable for JBoss. 

Note: I have simplified the initEnumValues(), too. The Class.getDeclaredMethod and Method.invoke do not need the second parameter - less memory garbage.

> 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.
