3 months have passed since the bug was observed and no new occurrences since then. Closing as "Cannot Reproduce".
02-11-2022
Right, maybe we should just close this as Cannot Reproduce then.

> This also happened once on Linux aarch64. Hard to say were those failures related. The failures happened with an adhoc build, so may be related to the particular changes tested there. (Also, it happened a couple weeks before the bug was filed.)

If the callee is unloading, then CodeCache::make_marked_nmethods_deoptimized() will skip it, so we need to be careful about calling into nmethods that are unloading. One known example that was recently fixed is JDK-8294538, but I'm not sure that bug applies here. I think it requires concurrent unloading with ZGC, not G1.
25-10-2022
This also happened once on Linux aarch64.
24-10-2022
Yes, the crash was observed once on an AMD EPYC machine after 19h uptime: Host: AMD EPYC 7J13 64-Core Processor, 12 cores
12-09-2022
If this only happens on AMD EPYC, then possibly related to JDK-8258825.
12-09-2022
A relevant change recently: JDK-8288064

Some observations from hs_err file: the failure happens when verification check fails on receiver at invokeinterface call: Event: 69078.547 Thread 0x000001903e88daf0 Uncommon trap: trap_request=0xffffff37 fr.pc=0x0000019028547178 relative=0x0000000000000298 Event: 69078.547 Thread 0x000001903e88daf0 Uncommon trap: reason=receiver_constraint action=none pc=0x0000019028547178 method=scala.collection.IndexedSeqOptimized$class.foreach(Lscala/collection/IndexedSeqOptimized;Lscala/Function1;)V @ 3 c2 ;*invokeinterface length {reexecute=0 rethrow=0 return_oop=0} ; - scala.collection.IndexedSeqOptimized$class::foreach@3 (line 32) ; - scala.collection.mutable.WrappedArray::foreach@2 (line 35) But top nmethod being deoptimized has patched verified entry point: Compiled method (c2) 69078562 3813251 4 scala.collection.mutable.WrappedArray::foreach (6 bytes) main code [0x0000019028546ee0,0x00000190285472b0] = 976 [Verified Entry Point] 0x0000019028546f00: e99b 3bbf fdff ff55 There had been some class loading happening right before the crash which could invalidate CHA invariants. Overall, it's suspicious why a method with patched verified entry point was called. A concurrency issue when invalidating affected nmethods would explain the failure.
10-08-2022
Vladimir, could you please take a look?
04-08-2022
ILW = Fatal error during deoptimization, only showed up once with long running benchmark, no workaround but disable compilation of affected method or potentially disable CHA = HLM = P3
04-08-2022
Failing code was added by JDK-8268405 in JDK 17.
