These functions cast oops to arrayOop without first checking that the `obj` argument is an array. It turns out that TestIntrinsics.java sends in non-array objects.
I found this when I worked on something else and changed `obj->is_null_free_array()` to `obj->klass()->is_null_free_array_klass()`, and the latter asserted because `obj` was a String and not an array. ------------- Commit messages: - 8380902: [lworld] Type confusion in jvm.cpp functions Changes: https://git.openjdk.org/valhalla/pull/2261/files Webrev: https://webrevs.openjdk.org/?repo=valhalla&pr=2261&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8380902 Stats: 42 lines in 1 file changed: 31 ins; 0 del; 11 mod Patch: https://git.openjdk.org/valhalla/pull/2261.diff Fetch: git fetch https://git.openjdk.org/valhalla.git pull/2261/head:pull/2261 PR: https://git.openjdk.org/valhalla/pull/2261
