This fix was originally proposed by @mruzicka in PR #16 which was closed several months ago without being integrated. At the time we didn't have a test case that was failing.
While evaluating a bug that I filed, [JDK-8235843](https://bugs.openjdk.java.net/browse/JDK-8235843), I discovered that that bug was a duplicate of this one. The original proposed fix is correct, although I modified it slightly to add a try / finally so that the secondary event loop will be terminated even if the setScene throws an exception. I also added a unit test. Since the bulk of the fix is from PR #16, I will add the contributor of that PR.
NOTE to reviewers: I pushed two commits to my branch. The first is exactly the commit created for PR #16 and the second is the unit test along with the fix to the code to add try / finally. As always, they will be squashed into a single commit by Skara.
- Add automated tests, enclose the latch in try/finally,
