Different array layouts result in distinct array klass metadata which are stored in a linked list with the base ObjArrayKlass acting as the head. Multiple layouts are currently uncommon, so this assert was sufficient:
`assert(objarray_k == k || objarray_k->next_refined_array_klass() == k) failed: must be` This assert is not correct since `k` could refer to another refined array klass further down the linked list. This patch corrects this assert by adding a find method to iterate through the linked list in case there are multiple layouts for the same type. A new test was added to catch this failure. Verified with tier 1-5 tests. ------------- Commit messages: - Added new test case - Fixed small bug in filemap - 8377791: [lworld] Assert in java_lang_Class::restore_archived_mirror Changes: https://git.openjdk.org/valhalla/pull/2095/files Webrev: https://webrevs.openjdk.org/?repo=valhalla&pr=2095&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8377791 Stats: 152 lines in 6 files changed: 149 ins; 0 del; 3 mod Patch: https://git.openjdk.org/valhalla/pull/2095.diff Fetch: git fetch https://git.openjdk.org/valhalla.git pull/2095/head:pull/2095 PR: https://git.openjdk.org/valhalla/pull/2095
