It looks like Oracle is planning to deprecate the SAX1 classes such as
DocumentHandler in JDK 9. Seems reasonable.
However they are also planning to deprecate the namespace aware
org.xml.sax.helpers.XMLReaderFactory in favor of SAXParserFactory (not
namespace aware by default). This seems to me to be backwards. Should
we push back on this?
It's been in there already since at least jdk7, so there's probably not
much hope of changing the default behavior. It's only one method call
to set it up for namespaces: setNamespaceAware(). Not too bad.
