-------------------------------------

             Summary: SCR Generator fails with a NPE in case a class level Reference doesn't define a referenceInterface
                 Key: FELIX-4192
                 URL: https://issues.apache.org/jira/browse/FELIX-4192
             Project: Felix
          Issue Type: Bug
          Components: Maven SCR Plugin
    Affects Versions: scr generator 1.8.0
         Environment: JDK7
            Reporter: Daniel Kuffner
            Priority: Minor


Consider following simple component:
{code}
@Component
@Reference(name="a", bind="setA", unbind="unsetA")
public class MyJavaClass {
}
{code}

the generator will fail with a NPE (see stacktrace). It would be preferable if the generator will fail with a usfull error message.

Stacktrace:
{code}
java.lang.NullPointerException
