Misleading definition error for decorator with observer method
--------------------------------------------------------------

                 Key: WELD-987
                 URL: https://issues.jboss.org/browse/WELD-987
             Project: Weld
          Issue Type: Bug
    Affects Versions: 1.1.2.Final
         Environment: JBoss AS7
            Reporter: Martin Kouba
            Priority: Minor


CDI 1.0 section 10.4.2 states:
"Interceptors and decorators may not declare observer methods. If an interceptor or decorator has a method with a paramet-
er annotated @Observes, the container automatically detects the problem and treats it as a definition error."

Following definition error is detected for decorator with observer method: *WELD-001419 - DECORATOR_CLASS_NOT_BEAN_CLASS_OF_DECORATOR*

New definition error like *DECORATORS_CANNOT_HAVE_OBSERVER_METHODS* would be more appropriate.

TCK test for this scenario (CDI 1.1 master branch):
