Upgrade from 4.4 issue

GregH

Ok, I have upgraded from 3.x to version "4.4 build 649" and everything works fine. Next i updated MySQL, Java etc and all is still ok.

However, any upgrade past this 5.x, 6.x fails and the browser is displaying a Null pointer exeption error.

I have no custom plugins but I get an error in the log;

2013-06-20 15:28:15,280 localhost-startStop-1 INFO [atlassian.plugin.manager.DefaultPluginManager] Initialising the plugin system

2013-06-20 15:28:16,827 localhost-startStop-1 ERROR [atlassian.event.internal.AsynchronousAbleEventDispatcher] There was an exception thrown trying to dispatch event 'com.atlassian.plugin.event.events.PluginFrameworkStartingEvent@16d36a5' from the invoker 'SingleParameterMethodListenerInvoker{method=public void com.atlassian.plugin.osgi.container.felix.FelixOsgiContainerManager.onStart(com.atlassian.plugin.event.events.PluginFrameworkStartingEvent), listener=com.atlassian.jira.plugin.JiraOsgiContainerManager@1ba994b}'

and this appears to be where the failure starts.

Any help is much appreciated.

The error is related to corrupted plugin cache. In attempt to fix the problem, try to clear your plugin cache. To do this, access your JIRA Home folder. Then, access the 'Plugins' folder. Delete the '.osgi-plugins' and the '.bundled-plugins' folders. Next, restart JIRA.
