Hi- It appears to be an issue with the GH webhook firing before the mergeability is computed.
When that happens, GH gives "null" to the mergeability field, when Jenkins is expecting true/false. Then Jenkins treats the branch as unmergeable and refuses to build it. I posted a comment to GH for the branch source and the GH Api plugins -- hopefully that will close the loop.
