Bug in the Mollom for Java library
FYI, both of the get*Captcha methods in the XmlrpcMollom class have a bug. The sessionId is being assigned the url value and the url is never being set.
Lines (in XmlrpcMollom.getImageChaptcha and XmlrpcMollom.getAudioCaptcha) currently read:
result.sessionId = captcha.get("session_id");
result.sessionId = captcha.get("url");
but should read:
result.sessionId = captcha.get("session_id");
result.url = captcha.get("url");
