[jdk17u-fix-request] Approval Request from Martin This backport fixes build warnings with GCC 11 as described in JDK-8297426. It doesn't apply cleanly, but resolution was simple and has been reviewed. The original change didn't cause any regression. The backport has been tested in our nightly tests.
