Description

Since we now have support for BBs in UnsafeByteOperations#unsafeWrap(ByteBuffer) . So for the non - java clients while creating the PB result we could avoid the copy to an temp array.
Since we have a support to write to BB in ByteOutput having a result backed by Bytebuffer should be fine.
