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: 4.2.5.Final, 4.3.2.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 4.2.6.Final, 4.3.3.Final {{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.
