[jboss-jira] [JBoss JIRA] (WFLY-4153) Incorrect interface definition in ejb-jar.xml for entity beans shows just NullPointer exception

Incorrect interface definition in ejb-jar.xml for entity beans shows just NullPointer exception ----------------------------------------------------------------------------------------------- Key: WFLY-4153 URL: https://issues.jboss.org/browse/WFLY-4153 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 9.0.0.Alpha1 Reporter: Chao Wang Assignee: Chao Wang Priority: Minor {noformat} In case that you specify interface type for entity bean in ejb-jar.xml that does not correspond with definition in the class of the bean then just Null Pointer exception is shown without any other info what's happening. I mean when you define bean through interface as remote and the ejb-jar.xml describes bean interfaces as local {code} public interface SomeBean extends EJBObject { ... } public interface SomeBeanHome extends EJBHome { ... } {code} and the ejb-jar.xml looks like {code} <ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd" version="3.1"> <enterprise-beans> <entity> <ejb-name>SomeBean</ejb-name> <local-home>package.SomeBeanHome</local-home> <local>package.SomeBean</local> <ejb-class>package.SomeBeanBean</ejb-class> <persistence-type>Bean</persistence-type> <prim-key-class>java.lang.Integer</prim-key-class> <reentrant>true</reentrant> </entity> </enterprise-beans> </ejb-jar> {code} then NullPointerException is thrown {code} ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC00001: Failed to start service jboss.deployment.unit."entitybeanbmp.jar".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.unit."entitybeanbmp.jar".INSTALL: JBAS018733: Failed to process phase INSTALL of deployment "entitybeanbmp.jar" at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:123) [jboss-as-server-7.2.0.Alpha1-SNAPSHOT.jar:7.2.0.Alpha1-SNAPSHOT] at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1811) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) [rt.jar:1.6.0_23] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) [rt.jar:1.6.0_23] at java.lang.Thread.run(Thread.java:662) [rt.jar:1.6.0_23] Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS011058: Failed to install component SimpleBMPBean at org.jboss.as.ee.component.deployers.ComponentInstallProcessor.deploy(ComponentInstallProcessor.java:102) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:116) [jboss-as-server-7.2.0.Alpha1-SNAPSHOT.jar:7.2.0.Alpha1-SNAPSHOT] ... 5 more Caused by: java.lang.NullPointerException at org.jboss.as.ejb3.component.entity.EntityBeanObjectViewConfigurator$2.configureDependency(EntityBeanObjectViewConfigurator.java:108) at org.jboss.as.ejb3.component.entity.EntityBeanObjectViewConfigurator$2.configureDependency(EntityBeanObjectViewConfigurator.java:105) at org.jboss.as.ee.component.deployers.ComponentInstallProcessor.deployComponent(ComponentInstallProcessor.java:139) at org.jboss.as.ee.component.deployers.ComponentInstallProcessor.deploy(ComponentInstallProcessor.java:95) ... 6 more {code} instead of some informative one. {noformat}
