Testing observed a few failures after JDK-8278387. On RISC-V, we followed JDK-8278489: The reason for the failures is in the native-wrappers, in the +UseHeavyMonitors paths, we don't preserve the result register after the native call.

Hotspot/jdk tier1 passed on the unmatched with -XX:+UseHeavyMonitors, and all jtregs were tested on Qemu without new failures.
