Code and summary of the problem
Code and logs: see issue17052.tar.gz. The code Test.java is a bit long because I ain't able to reduce it.
This seems to be the most reproducible problem out of the 12 as mentioned in our previous chat. I can reproduce exactly the same assertion failure (Scavenger.cpp:1669) 3 times out of 4 runs. I put logs of all these 4 runs in the link above, each in a directory named log.XXXXX. Hope the same frequency applies to you too. It makes OpenJ9 to crash in GC and should be a JIT bug since there aren't any crash if -Xint is enabled.
The test exited with code 255 and the assertion log (log.bOTRV, log.D1Uma, log.RtuV0) looks like
