RFR: 8153044: Allow a property to control location of tzdb.dat file

[Seán Coffey]

I'll (reluctantly) close this out then. I do think it was a convenient 
and low-maintenance feature that would allow end users the ability to 
bounce applications in an ordered fashion in order to pick up new tzdata 
rules. I'll investigate the upgradeable module approach.

Regards,
Sean.
