The test expects folding of `arrayElement == oArr` in the flat array array loop version which does not happen anymore when the flat array element can be null with `-XX:+UseNullableValueFlattening` (because `oArr` can be null as well). I adjusted the test so that C2 can deduce that `oArr` is never null and can therefore fold the check.
Thanks,
Tobias
