Ariel Weisberg commented on CASSANDRA-13906:
--------------------------------------------
If you implement Closable it's going to cause warnings any place that doesn't
use try with resources. Given the other usages I think what you have done is
probably fine although you can still switch to try with resources.

> When running dtests for trunk (4.x) that perform some streaming, sometimes a
> {{ByteBuf}} is not released properly, and we get this error in the logs
> (causing the dtest to fail):

> Slf4JLogger.java:176 - LEAK: ByteBuf.release() was not called before it's
> garbage-collected. Enable advanced leak reporting to find out where the leak
> occurred. To enable advanced leak reporting, specify the JVM option
> '-Dio.netty.leakDetection.level=advanced' or call
> ResourceLeakDetector.setLevel() See
> http://netty.io/wiki/reference-counted-objects.html for more information.
