/**
 * Unit test for
 *
 *  https://glassfish.dev.java.net/issues/show_bug.cgi?id=8565
 *  ("[SPEC] Restricted ServletContextListeners")
 * and
 *   https://glassfish.dev.java.net/issues/show_bug.cgi?id=10736
 *   ("two different ServletContext instances servicing the same application")
 *
 * This unit test declares a ServletContainerInitializer, which registers
 * a ServletContextListener, which in turn adds a ServletContext attribute
 * when it is invoked at its contextInitialized method. The test then accesses
 * a Servlet which checks for the presence of this ServletContext attribute,
 * and will throw an Exception if the attribute is missing.
 *
 * This unit test also makes sure that the ServletContextListener registered
 * by the ServletContainerInitializer is restricted by checking that any
 * attempt by it to register a Servlet will fail and result in an
 * UnsupportedOperationException.
