[hibernate-issues] [Hibernate-JIRA] Commented: (HV-362) Including Annotation Processor in Eclipse results in java.lang.OutOfMemoryError: Java heap space

[Gunnar Morling (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HV-362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38295#action_38295 ] 

Gunnar Morling commented on HV-362:
-----------------------------------

I checked the AP sources and didn't find any remarkable static maps or similar. 

A minimal source project which shows the error when the AP is applied would be of great help. Does the OutOfMemoryError also occur when using the AP with javac or only within Eclipse?
