RFR: 8378792: ObjectMethods.bootstrap missing getter validation

Thu Feb 26 19:22:09 UTC 2026

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.
