I will investigate.

I re-ran these tests on Java 8 and Java 10, it passed. Might be a machine issue. I will try re-producing on the failed machines.

These tests passed on previously failed machines. I suggest to close this issue for now. We can re-open if this failure is seen again.

There is another failure on Java 8. Both the Java 8 failure and the failure in the above comment (Java 10) are running on the same machine. I will re-try on that machine.

It is a test/timing issue. I will fix this.
