Hi Christian, thanks so much for your testing and feedback! I'll look into it ASAP. I had only tested in `release` mode before, which might explain why `jtreg:test/hotspot/jtreg/compiler` and `jtreg:test/hotspot/jtreg/vmTestbase` passed on my end.

Just a heads-up: I'll be taking a week off for the National Day holiday starting tomorrow, so my replies might be a bit delayed. I apologize in advance :P
