This is a side-effect of the join query optimization work we did for
2.2. The new join engine has trouble handling OR constraints that
reference both sides of a join.
The best workaround for now is to split your query into two parts around
the OR constraints, and then merge the results in client code.
See JCR-2852 [1] for more background on this issue. I'm hoping to have a
solution ready in time for Jackrabbit 2.3.
