Subject [jira] Updated: (MNG-3580) FATAL ERROR and NPE on start
Date Thu, 11 Sep 2008 18:06:49 GMT

     [ http://jira.codehaus.org/browse/MNG-3580?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joakim Erdfelt updated MNG-3580:
--------------------------------

    Attachment: MNG-3580-ibm-jdk-issues.zip

Attaching a project with a simple case that shows that the IBM JDK fails while the SUN JDK
works.

This example needs more work to show the same NPE's found in other more complex projects.
 

I'll attach another example when I get a use-case that is repeatable.
