[ChrisMisan]

@Dr15Jones could you explain why there are differences in the JetMET?

[Dr15Jones]

@ChrisMisan given that MagFieldConfigDBWriter does not appear in any of the standard configurations, it is pretty safe to say that module is never run in any of the test release validation jobs. So the differences are most likely caused by instability in the reconstruction code itself where it does not always give back the same results when run again.
