   I read the Javadoc and 
[ByteBuffer.wrap](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/ByteBuffer.html#wrap(byte%5B%5D))
 does not copy the bytes but more like creating a view. I assume this means 
there is no expensive copy operation.
   
   Is the modification for this PR about performance improvement or something 
else?
