use of org.eclipse.scout.rt.server.commons.cache.ICacheEntry in project scout.rt by eclipse.

the class ServiceTunnelServletTest method testLookupScoutServerSessionOnHttpSessionMultipleThreads.

 * Calls {@link ServiceTunnelServlet#lookupServerSessionOnHttpSession(ServerRunContext) in 4 different threads within
 * the same HTTP session. Test ensures that the same server session is returned in all threads and that
