Fix Version/s: 3.1.0
2.8.3

3.0.0-beta1
2.9.0
Status: Resolved (was: Patch Available)
Thanks [~manojg] and [~zhz]. I have committed patch to trunk, branch-3.0,
branch-2, branch-2.8 and branch 2.8.2. Besides the branch-2 diff mentioned
above, the patch for branch-2.8/branch.2.8.2 is slightly different in the unit
tests as maintenance state only exists in branch-2 and above.
