Null Pointer Exception getting text length

There needs to be a guard for NPE.

getTextLength() below causes an NPE. I have been through this with a debugger and reader is NOT null. This should return 0 like getTextOffset() does.

AbstractXMLStreamReader reader = null;
try {
reader = new MappedXMLStreamReader(jsonObject);
System.out.println("Version: " + reader.getVersion());
System.out.println("Count: " + reader.getAttributeCount());
while (reader.hasNext())

{ System.out.println("************************"); System.out.println("Element Text: " + reader.getElementText()); System.out.println("Local Name: " + reader.getLocalName()); System.out.println("Text Start Offset: " + reader.getTextStart()); System.out.println("Text Length: " + reader.getTextLength()); System.out.println("Text: " + reader.getText()); System.out.println("PIData: " + reader.getPIData()); System.out.println("PITarget: " + reader.getPITarget()); }

} finally

{ reader.close(); }

{"@type-key":"WiFiStation","$":"WiFi Device"}
