[jira] Resolved: (WW-3163) NPE on JBoss for
struts.convention.classes.reload=true
[ https://issues.apache.org/struts/browse/WW-3163?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wes Wannemacher resolved WW-3163.
---------------------------------
Resolution: Fixed
Fix Version/s: 2.1.7
Assignee: Wes Wannemacher
I can fix the NPE, but it does not make class reloading work on JBoss, I am closing this issue for now and will come back to JBoss support once I have had a chance to work with it a little more.
