Synchronizing access to SimpleDateFormat

Question

The javadoc for SimpleDateFormat states that SimpleDateFormat is not synchronized.

\"Date formats are not synchronized. It is recommended to create

Answer 1

I would say, create a simple wrapper-class for SimpleDateFormat that synchronizes access to parse() and format() and can be used as a drop-in replacement. More foolproof than your option #2, less cumbersome than your option #3.

Seems like making SimpleDateFormat unsynchronized was a poor design decision on the part of the Java API designers; I doubt anyone expects format() and parse() to need to be synchronized.
