I included the feedback provided by Romain. But this code does not give deprecation warning when both properties present
in the config. If this is not a problem, I will remove this requirement from the itests, because there are two tests that expect a warning to be given in this case as well.

David asked for this: "any use of mp.jwt.tomee.allow.no-exp should get a warning log message"
