Currently MessagePack.newDefaultUnpacker(ByteBuffer buffer) doesn't support HeapByteBuffer
When passing Read Only ByteBuffer, following exception happened. Because HeapByteBfuferR.hashArray() and HeapByteBfuferR.isDirect() returns false.
throw new IllegalArgumentException("Only the array-backed ByteBuffer or DirectBuffer is supported");

I want to unpacking HeapByteBufferR without copying bytes. Because I save msgpack data in BigTable, and BigTable library returns ByteString, and it only able to be no-copy converted to HeapByteBufferR with asReadOnlyByteBuffer().
