Unable to login Reseller UI after installing JDK8 builds

Installed JDK8 alpha builds in QA7. After starting all the services tried to login to the system with valid username and password, but login failed saying that "Your email address and/or password were not recognized". Seeing the following exception in the tomcat log.
