Description Eike Stepper CLA 2012-01-13 07:35:48 EST 
Cloned from: 368223: LoadRevisionsRequest with CDOFetchRuleManager enabled leads sometimes to NPE
https://bugs.eclipse.org/bugs/show_bug.cgi?id=368223

Build Identifier: 

Below is the NPE. 

It looks like one of the revisions requested is not available anymore and that is not handled correctly.
We currently disabled the fetchrule manager. However, we find that this has a negative performance impact.
