I believe that this is related to the local JMX agent and the configuration of the hosts file. First, ensure your hosts file has an appropriate mapping of localhost to 127.0.0.1. Then, add the following VM option:

-Djava.rmi.server.hostname=localhost

If you are using IntelliJ, you can find instructions for adding this VM option here.
