Description
In our automation tests, we can see intermittent NPE with following stack trace:
20:01:38,985 ERROR [org.jboss.as.server.deployment] (MSC service thread 1-1) WFLYSRV0043: Deployment unit processor org.wildfly.extension.microprofile.config.smallrye.deployment.SubsystemDeploymentProcessor@54fd99c3 unexpectedly threw an exception during undeploy phase POST_MODULE of deployment "org.jboss.qa.management.ws.WebservicesWsdlHostIT.war": java.lang.NullPointerException at org.wildfly.extension.microprofile.config-smallrye@7.2.0.GA-redhat-00004//org.wildfly.extension.microprofile.config.smallrye.deployment.SubsystemDeploymentProcessor.undeploy(SubsystemDeploymentProcessor.java:102) at org.jboss.as.server@6.0.11.Final-redhat-00001//org.jboss.as.server.deployment.DeploymentUnitPhaseService.safeUndeploy(DeploymentUnitPhaseService.java:211) at org.jboss.as.server@6.0.11.Final-redhat-00001//org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:149) at org.jboss.msc@1.4.5.Final-redhat-00001//org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1738) at org.jboss.msc@1.4.5.Final-redhat-00001//org.jboss.msc.service.ServiceControllerImpl$StartTask.execute(ServiceControllerImpl.java:1700) at org.jboss.msc@1.4.5.Final-redhat-00001//org.jboss.msc.service.ServiceControllerImpl$ControllerTask.run(ServiceControllerImpl.java:1558) at org.jboss.threads@2.3.2.Final-redhat-1//org.jboss.threads.ContextClassLoaderSavingRunnable.run(ContextClassLoaderSavingRunnable.java:35) at org.jboss.threads@2.3.2.Final-redhat-1//org.jboss.threads.EnhancedQueueExecutor.safeRun(EnhancedQueueExecutor.java:1985) at org.jboss.threads@2.3.2.Final-redhat-1//org.jboss.threads.EnhancedQueueExecutor$ThreadBody.doRunTask(EnhancedQueueExecutor.java:1487) at org.jboss.threads@2.3.2.Final-redhat-1//org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1364) at java.base/java.lang.Thread.run(Thread.java:834) 20:01:38,986 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC000001: Failed to start service jboss.deployment.unit."org.jboss.qa.management.ws.WebservicesWsdlHostIT.war".POST_MODULE: org.jboss.msc.service.StartException in service jboss.deployment.unit."org.jboss.qa.management.ws.WebservicesWsdlHostIT.war".POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of deployment "org.jboss.qa.management.ws.WebservicesWsdlHostIT.war" at org.jboss.as.server@6.0.11.Final-redhat-00001//org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:151) at org.jboss.msc@1.4.5.Final-redhat-00001//org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1738) at org.jboss.msc@1.4.5.Final-redhat-00001//org.jboss.msc.service.ServiceControllerImpl$StartTask.execute(ServiceControllerImpl.java:1700) at org.jboss.msc@1.4.5.Final-redhat-00001//org.jboss.msc.service.ServiceControllerImpl$ControllerTask.run(ServiceControllerImpl.java:1558) at org.jboss.threads@2.3.2.Final-redhat-1//org.jboss.threads.ContextClassLoaderSavingRunnable.run(ContextClassLoaderSavingRunnable.java:35) at org.jboss.threads@2.3.2.Final-redhat-1//org.jboss.threads.EnhancedQueueExecutor.safeRun(EnhancedQueueExecutor.java:1985) at org.jboss.threads@2.3.2.Final-redhat-1//org.jboss.threads.EnhancedQueueExecutor$ThreadBody.doRunTask(EnhancedQueueExecutor.java:1487) at org.jboss.threads@2.3.2.Final-redhat-1//org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1364) at java.base/java.lang.Thread.run(Thread.java:834) Caused by: java.lang.IllegalStateException: No ConfigProviderResolver implementation found! at org.eclipse.microprofile.config.api@1.3.0.redhat-00001//org.eclipse.microprofile.config.spi.ConfigProviderResolver.instance(ConfigProviderResolver.java:122) at org.wildfly.extension.microprofile.config-smallrye@7.2.0.GA-redhat-00004//org.wildfly.extension.microprofile.config.smallrye.deployment.SubsystemDeploymentProcessor.deploy(SubsystemDeploymentProcessor.java:67) at org.jboss.as.server@6.0.11.Final-redhat-00001//org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:144) ... 8 more
further on, there is also following error in the server.log (it has been dealt in WFWIP-64, although in different circumstances, I guess):
20:01:39,164 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([("deployment" => "org.jboss.qa.management.ws.WebservicesWsdlHostIT.war")]) - failure description: {"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.\"org.jboss.qa.management.ws.WebservicesWsdlHostIT.war\".POST_MODULE" => "WFLYSRV0153: Failed to process phase POST_MODULE of deployment \"org.jboss.qa.management.ws.WebservicesWsdlHostIT.war\" Caused by: java.lang.IllegalStateException: No ConfigProviderResolver implementation found!"}} 20:01:39,169 INFO [org.jboss.as.server] (Controller Boot Thread) WFLYSRV0010: Deployed "org.jboss.qa.management.ws.WebservicesWsdlHostIT.war" (runtime-name : "org.jboss.qa.management.ws.WebservicesWsdlHostIT.war") 20:01:39,171 INFO [org.jboss.as.controller] (Controller Boot Thread) WFLYCTL0183: Service status report WFLYCTL0186: Services which failed to start: service jboss.deployment.unit."org.jboss.qa.management.ws.WebservicesWsdlHostIT.war".POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of deployment "org.jboss.qa.management.ws.WebservicesWsdlHostIT.war"
The NPE itself goes from the 'undeploy' method in SubsystemDeploymentProcessor. Although, according to the surrounding log messages (longer test log is attached [^NPE-server.log]), the server is still in the boot process by that time.
This NPE happens quite rarely so it looks like some kind of a race-condition is in place. So far we have seen this only on Windows with JDK-11 combination but cannot say it does not affect other platforms for sure.
Also, we have not seen it with latest WildFly nightly builds too (WildFly revision 353b95ef201c18dbd465087f520392c8525a2213) (yet?).
