Chris Twiner updated MUSE-297:
------------------------------
Fix Version/s: 2.2.1
Assignee: Chris Twiner (was: Dan Jemiolo)
Looks like a good candidate for 2.2.1 as its truly private, and only static
methods access it.

> The XsdUtils class uses a static SimpleDateFormat object to format date
> objects (see below). According to JDK:
> >>>
> Synchronization
> Date formats are not synchronized. It is recommended to create separate
> format instances for each thread. If multiple threads access a format
> concurrently, it must be synchronized externally.
> <<<
> We did observe strange exceptions from that class when the code runs in
> multi-threaded environment. This forces us to put a hard sync. on unmarshal
> ManagementEvent objects.
> ------
> public class XsdUtils
> {
> //
> // Used to format dates in the XMLSchema dateTime format
> //
> private static DateFormat _FORMATTER =
> new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
