----------------------------------------
Hi [~xiaochen],
Thanks for working on this. i took a look, only one comment:
Can we do the exception warn log unconditionally instead of just when doAudit
is true? or if there is any concern?
Thanks.

> overriding Jersey's ExceptionMapper.
> This behavior is okay, but in the logs we'll see an ERROR audit log, but
