------------------------------------

             Summary: Inefficent ProtobufUtil.fromWrappedByteArray(ImmutableSerializationContext ctx, byte[] bytes) 
                 Key: IPROTO-130
                 URL: https://issues.redhat.com/browse/IPROTO-130
             Project: Infinispan ProtoStream
          Issue Type: Bug
    Affects Versions: 4.3.2.Final, 4.2.5.Final
            Reporter: Nistor Adrian


The implementation uses a ByteArrayInputStream that wraps the byte[], and then creates a CodedInputStream around it and this copies the input data to its own buffer. This should have been made more efficiently by building a CodedInputStream directly around the byte[] (which internally uses CodedInputStream.ArrayDecoder and doesn't need a buffer copy).
