["Jonathan Ellis (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-4942?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jonathan Ellis resolved CASSANDRA-4942.
---------------------------------------

    Resolution: Fixed

Fixed + committed.

Also fixed a tricky little problem with recyling a deallocated reader:

{code}
.       if (owner == null || buffer == null)
        {
            // The buffer == null check is so that if the pool owner has deallocated us, calling close()
            // will re-call deallocate rather than recycling a deallocated object.
            // I'd be more comfortable if deallocate didn't have to handle being idempotent like that,
            // but RandomAccessFile.close will call AbstractInterruptibleChannel.close which will
            // re-call RAF.close -- in this case, [C]RAR.close since we are overriding that.
            deallocate();
        }
        else
        {
            owner.recycle(this);
        }
{code}
