nodetool broken with java-11-openjdk-11.0.10.0.9-0.fc33.x86_64

I see error messages like

Cannot initialize optimized memory deallocator. Some data, both in-memory and on-disk, may live longer due to garbage collection.

Cassandra 3.11 appears to handle it better:

    static
    {
        boolean canClean = false;
        try
        {
            ByteBuffer buf = ByteBuffer.allocateDirect(1);
            ((DirectBuffer) buf).cleaner().clean();
            canClean = true;
        }
        catch (Throwable t)
        {
            logger.error("Cannot initialize un-mmaper.  (Are you using a non-Oracle JVM?)  Compacted data files will not be removed promptly.  Consider using an Oracle JVM or using standard disk access mode", t);
            JVMStabilityInspector.inspectThrowable(t);
        }
        isCleanerAvailable = canClean;
    }
