Comments
Closing this bug as a duplicate of JDK-8230565, with the recommendation to upgrade to 13.0.2 or 14 when released. Given ZGC's experimental status I find it unlikely that JDK-8230565 will be back ported all the way to to 11.

@Nils, I have attached the crash files to this issue. Let me know if they help the investigation. I don't know why, but the replay log is truncated at the end - unfortunately I don't have the original anymore.

ILW = Crash during compilation, with (experimental) ZGC, use different GC = HMM = P3
