Description

 

As of Java 9, the Transformer class's pretty-print feature doesn't define the actual format. Therefore, whitespace-only nodes will be outputted as well. This has been discussed in this JDK bug ticket. Also, Java 9's release note has explained this in the xml/jaxp section.

If we want our pretty-print method to always generate the same format under various Java versions, we need to provide a stylesheet file.
