      Description

        This is the umbrella issue for various @Contended touchups.

        The issues arguably manifest in the VM crashes/corruptions when specially-crafted @Contended classes are available. See linked issues for the observed failure modes.

        The more concrete failures are only happening on new hotspot/test/runtime/contended/{HasNonStatic,OopMaps} regression tests *with* the new asserts. This opens up the way to test the fix: revert the change, put the asserts back in, and watch the ClassFileParser::layout_fields asserts fire on fastdebug build.
