Description
Use case: build a magnolia webapp with a missing dependency which should be used by module (e.g. take the enterprise webapp bundle and remove the geoip2-0.7.0 jar used by the personalization module). Try to start magnolia and the error log you will get is:
ERROR info.magnolia.init.MagnoliaServletContextListener contextInitialized (MagnoliaServletContextListener.java:177) Oops, Magnolia could not be started java.lang.NullPointerException at info.magnolia.objectfactory.guice.GuiceUtils.hasExplicitBindingFor(GuiceUtils.java:155) at info.magnolia.objectfactory.guice.GuiceComponentProvider.getComponent(GuiceComponentProvider.java:99) at info.magnolia.objectfactory.Components.getComponent(Components.java:97) at info.magnolia.context.ContextFactory.getInstance(ContextFactory.java:72) at info.magnolia.context.MgnlContext.getSystemContext(MgnlContext.java:368) at info.magnolia.context.MgnlContext.release(MgnlContext.java:629) at info.magnolia.context.MgnlContext.doInSystemContext(MgnlContext.java:395) at info.magnolia.init.MagnoliaServletContextListener.startServer(MagnoliaServletContextListener.java:247) at info.magnolia.init.MagnoliaServletContextListener.contextInitialized(MagnoliaServletContextListener.java:173) at info.magnolia.init.MagnoliaServletContextListener.contextInitialized(MagnoliaServletContextListener.java:127) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4992) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5490) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1575) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1565) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745)
No clue about what's wrong, no info about missing classes... just a non-initialized context which has not been loaded for some reason, really hard to debug.
In order to provide a meaningful feedback I would change the build() method in GuiceComponentProviderBuilder which only catches CreationException:
try
{
Injector injector = Guice.createInjector(resolveStageToUse(), module);
return (GuiceComponentProvider) injector.getInstance(ComponentProvider.class);
}
catch (CreationException e)
{
log.error(
"Magnolia failed to load module configuration with types " + configuration
.getTypeMapping() + " and components " + configuration
.getComponents() + ". Please ensure you don't have any legacy modules present in your web application.",
e);
throw e;
}
with a catch-all ( catch (Throwable e) )... with this patch the error is definitively more useful (NB the original uncatched exception seemed to be swallowed somewhere):
ERROR info.magnolia.objectfactory.guice.GuiceComponentProviderBuilder build (GuiceComponentProviderBuilder.java:177) Magnolia failed to load module configuration with types [...] com.google.inject.internal.util.$ComputationException: com.google.inject.internal.util.$ComputationException: java.lang.NoClassDefFoundError: Lcom/maxmind/geoip2/DatabaseReader; at com.google.inject.internal.util.$MapMaker$StrategyImpl.compute(MapMaker.java:553) at com.google.inject.internal.util.$MapMaker$StrategyImpl.compute(MapMaker.java:419) at com.google.inject.internal.util.$CustomConcurrentHashMap$ComputingImpl.get(CustomConcurrentHashMap.java:2041) at com.google.inject.internal.FailableCache.get(FailableCache.java:50) at com.google.inject.internal.ConstructorInjectorStore.get(ConstructorInjectorStore.java:49) at com.google.inject.internal.ConstructorBindingImpl.initialize(ConstructorBindingImpl.java:125) at com.google.inject.internal.InjectorImpl.initializeBinding(InjectorImpl.java:507) at com.google.inject.internal.AbstractBindingProcessor$Processor$1.run(AbstractBindingProcessor.java:159) at com.google.inject.internal.ProcessedBindingData.initializeBindings(ProcessedBindingData.java:44) at com.google.inject.internal.InternalInjectorCreator.initializeStatically(InternalInjectorCreator.java:122) at com.google.inject.internal.InternalInjectorCreator.build(InternalInjectorCreator.java:106) at com.google.inject.Guice.createInjector(Guice.java:95) at com.google.inject.Guice.createInjector(Guice.java:83) at info.magnolia.objectfactory.guice.GuiceComponentProviderBuilder.build(GuiceComponentProviderBuilder.java:171) at info.magnolia.objectfactory.guice.GuiceComponentProviderBuilder.build(GuiceComponentProviderBuilder.java:189) at info.magnolia.cms.beans.config.ConfigLoader.load(ConfigLoader.java:153) at info.magnolia.init.MagnoliaServletContextListener$1.doExec(MagnoliaServletContextListener.java:250) at info.magnolia.context.MgnlContext$VoidOp.exec(MgnlContext.java:421) at info.magnolia.context.MgnlContext$VoidOp.exec(MgnlContext.java:418) at info.magnolia.context.MgnlContext.doInSystemContext(MgnlContext.java:392) at info.magnolia.init.MagnoliaServletContextListener.startServer(MagnoliaServletContextListener.java:247) at info.magnolia.init.MagnoliaServletContextListener.contextInitialized(MagnoliaServletContextListener.java:173) at info.magnolia.init.MagnoliaServletContextListener.contextInitialized(MagnoliaServletContextListener.java:127) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4992) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5490) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1575) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1565) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745)
The current behavior could really be a problem for many users, especially for anybody not using maven or integrating magnolia in complex webapps...
