I found out from our offline discussion that it failed only on Linux and not on other platforms.

Since it's **very** intermittent failure, and the test hasn't been on the problem list [since April](https://bugs.openjdk.org/browse/JDK-8144030), and there have been no reported incidents on Linux since then, I think we should not hide such failures behind additional attempts until we find out the cause.

I suggest adding some additional debugging information, such as saving a screenshot of what actually happened before the exception was thrown.
