             Summary: Avoid sticky byte array buffers in Zlib CompressionFilter
                 Key: DIRMINA-1103
                 URL: https://issues.apache.org/jira/browse/DIRMINA-1103
             Project: MINA
          Issue Type: Improvement
    Affects Versions: 2.0.21
            Reporter: Jörg Michelberger


For each Zlib instance there is a zStream instance which is equipped with new buffers for each in and out of inflate / deflate. This buffers are not released after each inflate / deflate. So the last compressed and uncompressed byte[] and its content for rx and tx is not garbage collectable on each session.

It would be great if there was a reset(zStream) method on Zlib which sets the in and out to static empty byte[] to release these buffers after usage quite before returning from Zlib.deflate and Zlib.inflate.

{{reset (zStream) {}}{{            zStream.next_in = EMPTY_BYTE_ARRAY;}}
{{            zStream.next_in_index = 0;}}
{{            zStream.avail_in = 0;}}
{{            zStream.next_out = EMPTY_BYTE_ARRAY;}}
{{            zStream.next_out_index = 0;}}
{{            zStream.avail_out = 0;}}

{{}}}
