Patch applies cleanly, but the test implicitly relies on the logging message added by [JDK-8291418](https://github.com/openjdk/jdk/commit/6065516bb3e0e445e9383718f539ec48440d6290#diff-3ff738a107928467669ff157a9bc20b2950c378a21ada38ac69237261a480985R1547). That change is too risky to backport, so I just pulled the logging message to make test work.

This is the additional line added to make the test work.
