Description

When using XMLConfiguration 2, tags containing only white spaces are not handled properly when xml:space="preserve" is set.  'null' is returned instead of the actual spaces.  To reproduce:

 

XMLConfiguration xml = new BasicConfigurationBuilder<>(
        XMLConfiguration.class).configure(
            new Parameters().xml()).getConfiguration();
FileHandler fh = new FileHandler(xml);
fh.load(new StringReader("<test xml:space=\"preserve\">    </test>"));
System.out.println("TEST: '" + xml.getString("") + "'");
// Outputs   -> TEST: 'null'
// Should be -> TEST: '    '
