The original sighting is for: vmTestbase/metaspace/staticReferences/StaticReferences.java Mikael's entry above is for: applications/runthese/RunThese30M.java And Gerard mentioned Java2Demo locally.

Is this bug known to affect anything besides a tier3 test and Java2Demo?
29-06-2018
Hit the issue locally running Java2Demo.jar - attaching hs_err file.

Tagged as 'promotion_blocker' since it looks like this bug was caused by JDK-8204157 which was pushed on 2018.06.27.
28-06-2018
This started failing after JDK-8204157 was pushed which modified gcm.cpp. Nils, can you please have a look?

ILW = Crash during compilation, single test at tier3, disable compilation of affected method = HMM = P2
