    Description

      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}
