Minor Description
tTestXPathRecordReader.testUnsupported_Xpaths covers some negative cases for xpath
While working on SOLR-12555, found that, here NPE thrown as rr is never set not the expected exception
try {
rr.addField("bold" ,"b", false);
fail("A RuntimeException was expected: 'b' xpaths must begin with '/'.");
}
catch (RuntimeException ex) { }
