If cache is configured, but not yet used, and than I flush all caches this happens:
2016-03-15 14:33:25,630 WARN info.magnolia.module.cache.app.CacheToolsPresenter#flushAllCaches.144 Unable to flush all caches. java.lang.NullPointerException at info.magnolia.module.cache.mbean.CacheMonitor.countFlush(CacheMonitor.java:123) at info.magnolia.module.cache.ehcache.EhCacheWrapper.clear(EhCacheWrapper.java:155) at info.magnolia.module.cache.commands.FlushCachesCommand.execute(FlushCachesCommand.java:67) at info.magnolia.module.cache.app.CacheToolsPresenter.flushAllCaches(CacheToolsPresenter.java:141) at info.magnolia.module.cache.app.CacheToolsViewImpl$4.buttonClick(CacheToolsViewImpl.java:209) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at com.vaadin.event.ListenerMethod.receiveEvent(ListenerMethod.java:508) at com.vaadin.event.EventRouter.fireEvent(EventRouter.java:198) at com.vaadin.event.EventRouter.fireEvent(EventRouter.java:161) at com.vaadin.server.AbstractClientConnector.fireEvent(AbstractClientConnector.java:977) at com.vaadin.ui.Button.fireClick(Button.java:393) at com.vaadin.ui.Button$1.click(Button.java:61) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497)
I think it should simply never give a NPE there.
Or if one insist that this situation is errorneous (which I doubt) it should throw some other exception, e.g. with information about which cache, which will be helpfull diagnosing the 'problem'.
