Description

When trying to run geode using JDK 9, gfsh start locator hangs.

With a little debugging, I tracked the problem down to some code that is trying to find jar file in the JDK directory. It's throwing an exception, which is getting silently swallowed. Below is the exception from a debugger.

We need to figure out a better way to get the status of a locator with JDK 9.
