    [ https://jira.jboss.org/jira/browse/JBIDE-2727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12428924#action_12428924 ] 

Snjezana Peco commented on JBIDE-2727:
--------------------------------------

This issue is caused by a memory leak in the JBoss XML editors.
It can be reproduced in the following way:
- close all editors and restart Eclipse
- try Anton's test case
You won't get the exception
- close all the editors
- open some JBoss XML editor (web.xml or faces-config.xml)
- switch to the Source tab
- close JBoss XML editor
- try Anton's test case again
You will get the exception because JBoss XML editor introduces a memory leak.

The check that Slava have added will prevent the exception, but won't fix the memory leak.
