>> From the error message, the cause of the failure is that 'UseRVV' was made diagnostic in [JDK-8343555](https://bugs.openjdk.org/browse/JDK-8343555). But the test was not updated to refect this. Instead of adding one extra `-XX:+UnlockDiagnosticVMOptions` option, this simply removed the use of `-XX:+UseRVV` from the test. The reason is that we have `-XX:+UseRVV` auto detected and enabled, so we will have RVV extension if we satisfy the test requirement:
