> URL: https://issues.apache.org/jira/browse/CASSANDRA-20677
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Local/Other
> Reporter: Sam Lightfoot
> Assignee: Sam Lightfoot

>
>
> Per comments in FileUtils::clean
> {code:java}
> // TODO Once we can get rid of Java 8, it's simpler to call
> sun.misc.Unsafe.invokeCleaner(ByteBuffer),
> // but need to take care of the attachment handling (i.e. whether 'buf' is a
> duplicate or slice) - that
> // is different in sun.misc.Unsafe.invokeCleaner and this implementation.
> {code}
> We can now use Unsafe.invokeCleaner to clean direct byte buffers which should
> tidy up the existing code.
