That code never should have compiled in the first place (though it wouldn't 
hurt my feelings any if it just made it automatically immutable for you given 
than all of the constructors are immutable - maybe that's what was happening 
before). There has to have been a compiler change which changed behavior. All 
TimeZone types have always had to be immutable.
