[GoogleCodeExporter]

What steps will reproduce the problem?
1. Call DiscoveryInformation's associate method in auth request servlet and 
store the returned object in seesion with: request.getSession().setAttribute
2. Later, in auth response servlet, get back object with: DiscoveryInformation 
dci = (DiscoveryInformation) request.getSession().getAttrbiute;
System.out.println("discovery information = " + dci.toString());
3. auth request url and return_to url both start with same hostname and ap 
context

What is the expected output? What do you see instead?
Expected to see string version of discovery information dump. Instead, Tomcat 
shows "org.openid4java.discover.DiscoveryInformation can't cast to 
org.openid4java.discover.DiscoveryInformation" strange error message.

What version of the product are you using? On what operating system?
version 0.9.8.741 on Windows 7 w/ Tomcat 6

Our test procedure:

RegisterService)
2.Auth ok, so Yahoo call backs our ReceiveResponse
