The team I'm working on has written a custom implementation of the ProxySelector class to dynamically handle proxying for all of our outbound connections. The custom ProxySelector still falls back to the default one, which will use the proxy system properties if they are set.
I noticed in our CXF client that if the proxy system properties are set, the custom ProxySelector never gets called, even if the HTTPClientPolicy on the client is left unchanged. After looking at the CXF code, it appears that the reason this happens is because org.apache.cxf.transport.http.ProxyFactory creates a Proxy object based on the system properties if there is not proxy configuration in the HTTPClientPolicy. That Proxy object eventually get passed as an argument to url.openConnection(), overriding our ProxySelector. I've been wrong before, but this doesn't seem to be intuitive behavior. I would expect that if the HTTPClientPolicy had not been configured with proxy settings that CXF would call the "no-arg" version of url.openConnection, regardless of whether or not the system properties are set. In this case, if the system properties are set, and no customizations have been made to the ProxySelector the default ProxySelector would still use the system properties. Am I off base here?
