Description
Since ~ 11th May / 12th May,  our JCK19 simple API suite  tests crash on Linux aarch64 . They run into the following guarantee .
Issue can be seen in the opt / product build results (seems Darwin aarch64 has similar issues); fastdebug shows an assertion instead.

Suite is executed with -Xcomp -Xbatch -XX:ReservedCodeCacheSize=512M -XX:-TieredCompilation , this has most likely an influence on the issue.
We run into the guarantee in  test  api/java_time/test/java/time/TestInstant.html  (see Current CompileTask:  output)

Checked that failed api/java_time/test/java/time/TestInstant.html jck test passed in JDK 19 ATR.

Fix request [17u] I backport this for parity with 17.0.5-oracle. A C2 fix we should backport before 8285923 Clean backport. SAP nightly testing passed.

OK, thanks for the additional info [~mbaesken]. I did a more detailed analysis and the bug is uncovered (but not necessarily caused) by JDK-8286163, which makes sense since it modifies java.time.Instant.
23-05-2022
Our tests on the 10th May (JDK-8285923 has been pushed on the 9th) were still good, did not show this issue.
23-05-2022
JDK-8285923 is suspected of causing these failures: it was integrated just two days before the failure observations, touched code around the failing assertion in macroAssembler_aarch64.cpp, and is a redo of JDK-8285802 which caused similar "Field too big for insn" failures. [~aph] could you have a look?

ILW = crash in product build; in JCK test using non-standard configuration; use default configuration = HML = P2

With fastdebug binaries we get a crash too in api/java_time/test/java/time/TestInstant.html (this time on mac aarch64). But this time an assertion (porbably because it is fastdenug) with a bit different backtrace. We again run with -Xcomp -Xbatch -XX:-TieredCompilation . # # A fatal error has been detected by the Java Runtime Environment: # # Internal Error (/darwinaarch64/jdk/src/hotspot/cpu/aarch64/macroAssembler_aarch64.cpp:2297), pid=51651, tid=41475 # assert(Rd != zr) failed: overflow in immediate operand # # JRE version: OpenJDK Runtime Environment (19.0) (fastdebug build 19-internal-adhoc.openjdk.jdk) # Java VM: OpenJDK 64-Bit Server VM (fastdebug 19-internal-adhoc.openjdk.jdk, compiled mode, compressed oops, compressed class ptrs, g1 gc, bsd-aarch64) # Core dump will be written.
