[jira] Updated: (WICKET-3050) AccessControlException thrown when security manager denies access

["Clint Checketts (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/WICKET-3050?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Clint Checketts updated WICKET-3050:
------------------------------------

    Attachment: enableReplaceObject_patch.txt

Here is a patch that catches the exception and logs it (though a log.debug or log.info would probably be better)

I'm not certain I understand the purpose of the enableReplaceObject call, so I'm not certain if the caught exception could lead to other problems.
