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

             Summary: ProtobufUtil.fromWrappedByteArray should not create a ByteArrayInputStream
                 Key: IPROTO-129
                 URL: https://issues.redhat.com/browse/IPROTO-129
             Project: Infinispan ProtoStream
          Issue Type: Bug
    Affects Versions: 4.3.2.Final
            Reporter: Dan Berindei


{{ProtobufUtil.fromWrappedByteArray}} wraps the {{bytep[]}} in a {{ByteArrayInputStream}} and uses that as an input for {{CodedInputStream}}. But that is inefficient, because {{CodedInputStream.StreamDecoder}} needs to allocate a buffer and copy from the stream into the buffer before processing. 

Instead we can pass the {{byte[]}} directly to {{CodedInputStream}} and use {{CodedInputStream.ArrayDecoder}}, which doesn't need a buffer.
