Warnings Cleanup in java.util.<various> (more from hack day)

[Xueming Shen]

The j.u.z.ZipEntry change should NOT be in as a warning cleanup. Will 
need further
evaluation/measurement, for example from performance point of view, the 
change
now creates a new Calendar instance instead of a Date object (Date class 
uses a
singleton BaseCalendar for the calculation, if I remember correctly) for 
each invocation.
