During review of Valhalla lworld vs mainline patch, I noticed Valhalla has a fix for a mainline issue where there is no getter validation for ObjectMethods.bootstrap. We should upstream this fix to mainline to make lworld cleaner and make mainline more robust. Before this fix, the invalid getters caused weird exceptions in method handle construction. Now they consistently throw IllegalArgumentException as specified. ------------- Commit messages: - 8378792: ObjectMethods.bootstrap missing getter validation Changes: https://git.openjdk.org/jdk/pull/29941/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=29941&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8378792 Stats: 68 lines in 2 files changed: 43 ins; 4 del; 21 mod Patch: https://git.openjdk.org/jdk/pull/29941.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/29941/head:pull/29941 PR: https://git.openjdk.org/jdk/pull/29941
