Bug 381447

Description Sam Davis 2012-06-01 18:39:45 EDT

* install http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/juno/RC2/eclipse-rcp-juno-RC2-win32.zip
* start up using an existing workspace last used with Eclipse 3.7.2
* the task list is empty, as in, no tasks, no find box or buttons, no widgets at all
* the only thing you can do from the task list is select the view menu > Refresh Search Index, and this produces the following exception:
