NPE is only a symptom for an empty InputStream which provide xml/json NormalizeNodeWriter classes. It looks like problem with jax-rs entity providers on jersey side. The describled behavior needs to be tested against 2.x jersey version.

Move to NETCONF project

Update:

Issue is seen on current master (Boron) branch as well

I was seeing the issue invoking RPC using curl from a remote machine. This seems to be a side-effect of “Expect: 100-continue” header which curl adds to the request (part of HTTP 1.1 spec). If this is disabled by using -H “Expect:” or -0 on curl command line, issue is not seen
