Hi Naresh,
This should have been fixed already in Jersey 2.18-SNAPSHOT version with
https://github.com/jersey/jersey/pull/149/ <
https://github.com/jersey/jersey/pull/149/>
Please allow some time to have this propagated to the publicly available
Jersey maven artifacts, or just wait for the 2.18 release (which would happen
in about 2-4 weeks from now).
HTH,
~Jakub
