http://stackoverflow.com/questions/26710286/cas-4-does-not-work-properly-with-cas-client-core-3-1-12
As title shown, currently i am using CAS 3.5.2, therefore i upgrade to CAS
4.i just change the user name casuser and mellon to admin admin. its a very
minimal changes.
therefore when i try to login, for example:
1 login, abcd/login
2 redirect to cas/login
3 after success logon, its redirect to abcd/login?st=xxxxxx with blank page.
do i miss somethings? or i need to change pom.xml?
below is part of my pom.xml

Therefore i checked the error code,view and breakpoint the source
code(package org.jasig.cas.client.validation;). in
Saml11TicketValidator.parseResponseFromServer, its because the response
result wasnt in expected therefore substring got problems. this 1 just
exception handling, is not a root cause.**The root cause is in
Saml11TicketValidator retrieveResponseFromServer, why CAS4 Return login
page(in my CAS4, is already login)??? is it a bug?**
note: my maven dependency is using cas-client-core-3.1.12.jar
