Accepted Answer

This is a bug in the current JDK implementation which has been fixed in the JDK8 implementation.Checkout this link for details https://bugs.openjdk.java.net/browse/JDK-7157360. There is a way to hack around this but Jersey team decided not to fix it https://github.com/eclipse-ee4j/jersey/issues/1639

2 solutions which I can think of

- use Apache Http Client which supports HttpPatch method

- use Jersey Client PostReplaceFilter but the Container code has to be modified and include X-HTTP-Method-Override header with value as PATCH while making a post request. Refer to http://zcox.wordpress.com/2009/06/17/override-the-http-request-method-in-jersey/ ]
