[gatein-issues] [JBoss JIRA] (GTNSSO-12) CASAgent Singleton causes issues when different Portal Container in the same JVM uses InitiateLoginFilter

CASAgent Singleton causes issues when different Portal Container in the same JVM uses InitiateLoginFilter --------------------------------------------------------------------------------------------------------- Key: GTNSSO-12 URL: https://issues.jboss.org/browse/GTNSSO-12 Project: GateIn SSO Issue Type: Bug Affects Versions: 1.1.1-GA Environment: OS X 10.8.2, Java 1.6, JBoss EPP 5.2.2, Reporter: Ray Tsang Assignee: Marek Posolda Labels: sso-agent Fix For: 1.2.0-Beta02 When 2 or more portal containers are configured with InitiateLoginFilter in web.xml, both InitiateLoginFilter instances gets CASAgent by CASAgent.getInstance(serverUrl,serviceUrl). However, the url may differ (especially the serviceUrl). Even though CASAgent.getInstance(...) takes in 2 arguments, it only stores a single singleton reference, hence whoever caused the single to instantiate first instances wins, and subsequent InitiateLoginFilter instances will get an instance with a different serverUrl/serviceUrl configuration. This causes CAS authentication to fail.
