             Summary: let NettyBufferPool extend PooledByteBufAllocator
                 Key: FLINK-7517
                 URL: https://issues.apache.org/jira/browse/FLINK-7517
             Project: Flink
          Issue Type: Sub-task
          Components: Network
    Affects Versions: 1.4.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber


{{NettyBufferPool}} wraps {{PooledByteBufAllocator}} but due to this, any allocated buffer's
{{alloc()}} method is returning the wrapped {{PooledByteBufAllocator}} which allowed heap
buffers again. By extending the {{PooledByteBufAllocator}}, we prevent this loop hole and
also fix the invariant that a copy of a buffer should have the same allocator.
