Major Description
I've faced an unexpected behavior testing my app trying to deal with a POST request for a REST service where my message is empty string. In this case, when using a JAXRSClientFactory proxy i get java.lang.IllegalStateException: Already connected when i sent an empty byteArray ... the proxy method never gets called. This does not happens when i sent any content ... the proxy method gets called. I think it could be a bug.
I have test case.
Here is the full trace:
