XsdUtils.getLocalTimeString not thread safe
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.
Can this be fixed quickly?
-thanks
