Minor If at Nuxeo startup there is a low-level exception thrown that is not a regular Exception, so any Error, then this exception is not caught and not logged but silently prevents Nuxeo startup. For instance:
ERROR [localhost-startStop-1] [org.nuxeo.runtime.deployment.NuxeoStarter] Exception during startup java.lang.NoSuchFieldError: userServerSideEncryption at org.nuxeo.ecm.core.storage.cloud.S3BinaryManagerExtended.setupBuilder(S3BinaryManagerExtended.java:129) at org.nuxeo.ecm.core.storage.cloud.S3BinaryManagerExtended.setupCloudClient(S3BinaryManagerExtended.java:55) at org.nuxeo.ecm.blob.AbstractCloudBinaryManager.initialize(AbstractCloudBinaryManager.java:114) at org.nuxeo.ecm.core.blob.BlobManagerComponent.getBlobProvider(BlobManagerComponent.java:172) at org.nuxeo.ecm.core.blob.BlobManagerComponent.registerBlobProvider(BlobManagerComponent.java:126) at org.nuxeo.ecm.core.blob.BlobManagerComponent.registerContribution(BlobManagerComponent.java:103) at org.nuxeo.runtime.model.DefaultComponent.registerExtension(DefaultComponent.java:53) at org.nuxeo.runtime.model.impl.ComponentInstanceImpl.registerExtension(ComponentInstanceImpl.java:209) at org.nuxeo.runtime.model.impl.RegistrationInfoImpl.activate(RegistrationInfoImpl.java:462) at org.nuxeo.runtime.model.impl.ComponentManagerImpl.activateComponent(ComponentManagerImpl.java:547) at org.nuxeo.runtime.model.impl.ComponentManagerImpl.activateComponents(ComponentManagerImpl.java:524) at org.nuxeo.runtime.model.impl.ComponentManagerImpl.start(ComponentManagerImpl.java:787) at org.nuxeo.runtime.osgi.OSGiRuntimeService.startComponents(OSGiRuntimeService.java:460) at org.nuxeo.runtime.osgi.OSGiRuntimeService.frameworkEvent(OSGiRuntimeService.java:475) at org.nuxeo.osgi.OSGiAdapter.fireFrameworkEvent(OSGiAdapter.java:223) at org.nuxeo.osgi.application.loader.FrameworkLoader.doStart(FrameworkLoader.java:226) at org.nuxeo.osgi.application.loader.FrameworkLoader.start(FrameworkLoader.java:125) at org.nuxeo.runtime.deployment.NuxeoStarter.start(NuxeoStarter.java:124) at org.nuxeo.runtime.deployment.NuxeoStarter.contextInitialized(NuxeoStarter.java:93) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4745) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5207) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:752) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:728) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:734) at org.apache.catalina.startup.HostConfig.deployDescriptor(HostConfig.java:630) at org.apache.catalina.startup.HostConfig$DeployDescriptor.run(HostConfig.java:1842) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:748)
