Hi, I see this comment on setDateFormat
If you need per-request configuration, use {@link #writer(DateFormat)} to * create properly configured {@link ObjectWriter} and use that; this because * {@link ObjectWriter}s are thread-safe whereas ObjectMapper itself is only * thread-safe when configuring methods (such as this one) are NOT called. Does this mean that ObjectMapper itself cannot be thread-safe when we set a date format ? Does this mean that DateFormat isn't thread-safe ? DateFormat's aren't thread-safe.
