Andy Wilkinson created WFLY-8515: ------------------------------------ Summary: Deployments fails if AsyncListener anywhere in a war implements a class that isn't on the classpath Key: WFLY-8515 URL: https://issues.jboss.org/browse/WFLY-8515 Project: WildFly Issue Type: Feature Request Affects Versions: 10.1.0.Final, 9.0.2.Final Reporter: Andy Wilkinson Assignee: Jason Greene Attachments: wildfly-problem.zip If a web application contains, anywhere in {{WEB-INF/classes}} or a jar in {{WEB-INF/lib}}, an {{AsyncListener}} that implements an interface that isn't on the classpath, deployment of the web application will fail. A concrete example is Spring Framework's {{spring-web}} module which contains [such a listener|https://github.com/spring-projects/spring-framework/blob/f716c8e...]. When a war file is deployed to Wildfly 9.0.2.Final with {{spring-web}} in {{WEB-INF/lib}} deployment fails: {noformat} ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2) MSC000001: Failed to start service jboss.deployment.unit."bootapp.war".POST_MODULE: org.jboss.msc.service.StartException in service jboss.deployment.unit."bootapp.war".POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of deployment "bootapp.war" at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:163) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1948) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1881) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.LinkageError: Failed to link org/springframework/http/server/reactive/ServletHttpHandlerAdapter$HandlerResultSubscriber (Module "deployment.bootapp.war:main" from Service Module Loader) at org.jboss.modules.ModuleClassLoader.defineClass(ModuleClassLoader.java:437) at org.jboss.modules.ModuleClassLoader.loadClassLocal(ModuleClassLoader.java:269) at org.jboss.modules.ModuleClassLoader$1.loadClassLocal(ModuleClassLoader.java:77) at org.jboss.modules.Module.loadModuleClass(Module.java:560) at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:197) at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:455) at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:404) at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:385) at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:130) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at org.jboss.as.server.deployment.reflect.DeploymentClassIndex.classIndex(DeploymentClassIndex.java:54) at org.jboss.as.ee.component.deployers.InterceptorAnnotationProcessor.processComponentConfig(InterceptorAnnotationProcessor.java:85) at org.jboss.as.ee.component.deployers.InterceptorAnnotationProcessor.deploy(InterceptorAnnotationProcessor.java:77) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:156) ... 5 more Caused by: java.lang.NoClassDefFoundError: org/reactivestreams/Subscriber at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:763) at org.jboss.modules.ModuleClassLoader.doDefineOrLoadClass(ModuleClassLoader.java:353) at org.jboss.modules.ModuleClassLoader.defineClass(ModuleClassLoader.java:432) ... 19 more Caused by: java.lang.ClassNotFoundException: org.reactivestreams.Subscriber from [Module "deployment.bootapp.war:main" from Service Module Loader] at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:205) at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:455) at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:404) at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:385) at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:130) ... 23 more {noformat} This listener is only ever actually registered when the {{Subscriber}} class is on the classpath so it seems unreasonable for it to cause a failure at deployment time.
