> NullPointerException in PortletEntityImpl.backupValues() under high load
> ------------------------------------------------------------------------
>
> Key: JS2-777
> URL: https://issues.apache.org/jira/browse/JS2-777
> Project: Jetspeed 2
> Issue Type: Bug
> Components: Portlet Entities and Preferences
> Affects Versions: 2.1.2
> Environment: apache tomcat 5.5.20, SuSe Linux
> Reporter: Vitaly Baranovsky
>
> There is NullPointerException in log when portal is running under high load.
> I've finded in all portal src places when using data, filled in backupValues(). Only PortletEntityImpl.reset() uses this data. But no one method in all portal src doesn't uses PortletEntityImpl.reset().
> It's looks like there is a sence to remove calls to backupValues() everywhere in portal src. Isn't it?
