Description

In 3.1 XmlRpcResponseParser.addResult(Object), the following unguarded code throws a ClassCastException:

Integer faultCode = (Integer) map.get("faultCode");

The server (in this case Bugzilla::WebService::Bug::get_bugs.pm) might be using the wrong type (String) for faultCode , but this exception hides the true error being reported so it would be nice if the code were guarded.

I'm using binaries from xmlrpc-3.1-bin.tar.gz.

(As an aside, I can't figure out what Object[] to send to get_bugs: neither Integer nor String works.)

java.lang.ClassCastException: java.lang.String incompatible with java.lang.Integer
