Description

When serializing XML a default namespace will throw a NPE in method serializeElement().

// Now write out the list of namespace declarations in this list that we constructed
// while doing the "set" processing.
if (writePrefixList != null) {
for (int i=0; i<writePrefixList.size(); i++) {
String prefix = (String) writePrefixList.get;
String namespace = (String) writeNSList.get;
========> if (prefix != null)

{ <<<<<<<<======= writer.writeNamespace(prefix, namespace); }

else

{ writer.writeDefaultNamespace(namespace); }

}
}

Fix is easy: Replace marked section with:

if ( ! "".equals(prefix)) {
