Subject [1/2] camel git commit: Convention over configuration
Date Tue, 31 Jan 2017 18:44:37 GMT
Repository: camel
Updated Branches:
  refs/heads/master 56d8b5514 -> 95078e405


Convention over configuration

Improvement in AbstractCamelInvocationHandler.invokeProxy, to auto detect if the invocation
is binding capable.

It is determined by checking the parameter count and annotation types on each parameter, and
only use binding if it is capable. Otherwise fallback on to the old bean invocation way.
