Verify with MBeanClient.java, it will succeed. 6) Run the CLI command: /subsystem=deployment-scanner/scanner=default:write-attribute(name=scan-enabled, value=false) 7) Delete the file $JBOSS_HOME/standalone/deployments/jboss-helloworld-1.0.war 8) Copy jboss-helloworld-2.0.war to $JBOSS_HOME/standalone/deployments. Version 2.0 has a dependency on a static module that does not exist 9) Run the CLI command: /subsystem=deployment-scanner/scanner=default:write-attribute(name=scan-enabled, value=true) 10) JBoss begins to undeploy version 1.0, and deploy version 2.0. Deployment of version 2.0 fails due to a missing module dependency. Deployment of version 2.0 rolls back. When deployment of version 2.0 fails, the undeploy of 1.0 tries to roll back. But since the war file was removed, the roll back of 1.0 fails and leaves the deployment in a bad state. 11) MBeanClient.java. It fails and a NullPointerException is generated on the server. Expected behaviour:- JBoss should not throw a NullPointerException. It should throw an informational exception such as javax.management.AttributeNotFoundException or similar.
