The WebSphere Deployer plugin is able to connect to the remote WAS 8.5.5.5 server, and stop/remove/install a WAR/EAR.

I can see the new app shows up on the WAS console as stopped, and the following line in the SystemOut.log

ADMA5013I: Application HelloWorldServlet installed successfully.

But the build just hung there forever, not able to start the app, and no error in the remote server log, only found the following error in the Jenkins log until I cancel the build:
