Description

JsonOutput is using a static SimpleDateFormat object. This is not a threadsafe use of that class.

See http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html#synchronization for more details.

I did create a test case for this, but these are hard cases to test and it looks pretty ugly. I will happily submit it, however, if it helps.
