On Linux, a null pointer exception is thrown when deploying an application using the wdeploy command-line utility. This happens at the end of the deploy, and only if it succeeds.

Workaround: The error seems to occur when wdeploy reads the stdout/stderr after execution of the reconfigure script following the deploy. The reconfigure should go through, but you should check to see if the server did indeed reconfigure by looking in the errors log for the reconfigure message. If the message is not there, then run the reconfigure script manually.
