Re: PATCH support on the client


Andy McCright
 

That is more-or-less my opinion too.  I'd prefer that we supported the patch() method fully (not optionally), but if the decision is support it optionally or not at all, I'd choose not at all.
 
On this topic, is it possible to remove the HttpUrlConnection restriction in Java 9 so that we could have more flexibility for future JAX-RS Client APIs?
 
Thanks,
 
Andy

Same feeling here.
