Description
Running a stress test on my application with a large number of concurrent clients, I'm getting the following exception:
Caused by: java.lang.NullPointerException at com.sun.faces.application.NavigationHandlerImpl$NavigationInfo.access$000(NavigationHandlerImpl.java:1364) [jsf-impl-2.2.5-jbossorg-3.jar:] at com.sun.faces.application.NavigationHandlerImpl.getNavigationMap(NavigationHandlerImpl.java:296) [jsf-impl-2.2.5-jbossorg-3.jar:] at com.sun.faces.application.NavigationHandlerImpl.getViewId(NavigationHandlerImpl.java:478) [jsf-impl-2.2.5-jbossorg-3.jar:] at com.sun.faces.application.NavigationHandlerImpl.getNavigationCase(NavigationHandlerImpl.java:149) [jsf-impl-2.2.5-jbossorg-3.jar:] at com.sun.faces.application.NavigationHandlerImpl.getNavigationCase(NavigationHandlerImpl.java:140) [jsf-impl-2.2.5-jbossorg-3.jar:]
This exception no longer occurs when the application has been warmed up by running a single request before going parallel.
The root cause appears to be in com.sun.faces.application.NavigationHandlerImpl:
private void createNavigationMaps() { if (null == navigationMaps) { NavigationMap result = null; NavigationInfo info = null; navigationMaps = new ConcurrentHashMap<String, NavigationInfo>(); result = new NavigationMap(); info = new NavigationInfo(); info.ruleSet = result; navigationMaps.put(ROOT_NAVIGATION_MAP_ID, info); } }
The member this.navigationMaps is set before ROOT_NAVIGATION_MAP_ID is put into the map, so another thread may get null from navigationMap.get(ROOT_NAVIGATION_MAP_ID) in method getNavigationMap().
