The test I added in this PR is based on @chhagedorn Test3.java. I was able to reproduce the issue on my end fairly easily.

I wasn't able to reproduce the issue using Test.java, how often does it reproduce for you with the flags that you listed at the top of Test.java ?

Thanks for testing @TobiHartmann !
