- JSecurity. This framework has been under active community development since its first release in April 2006, and was granted incubator status as a potential Apache Software Foundation community effort in June 2008. It is used by the Nexus and Grails projects, and the Nexus developers had many positive things to say about JSecurityit. JSecurity is also currently slated to be integrated with Restlet 1.2.
JSecurity is billed on its About page as "extremely easy to use and understand. An evaluating developer should grasp all the fundamentals within 10 minutes." (If true, this may enable us to fairly rapidly evaluate its design approach and capabilities, vis a vis Nuxeo's integral security support.) It is "POJO and interface based ... you can use it in any pojo container, servlet container, J2EE application server, or standalone application out of the box." This framework is licensed under an Apache 2.0 license, which may potentially be compatible with CollectionSpace licensing requirements.
One potential concern might be the state of user documentation (outside the Javadocs, which are claimed to be excellent) as of the current 0.9x releases. There is a long and helpful, threaded discussion on that topic on the JSecurity-Dev list.
