NullPointerException when attempting to get an InjectionTarget for an Interface Class
-------------------------------------------------------------------------------------

                 Key: WELD-763
                 URL: https://jira.jboss.org/browse/WELD-763
             Project: Weld
          Issue Type: Bug
            Reporter: Tom Fennelly

Simple enough to reproduce...

AnnotatedType<?> annotatedType = beanManager.createAnnotatedType(serviceType);
InjectionTarget injectionTarget = beanManager.createInjectionTarget(annotatedType);

Where serviceType is an Interface Class.  A NPE results on the following call to createInjectionTarget because serviceType has no constructors....

java.lang.NullPointerException
    at org.jboss.weld.util.Beans.getPostConstructMethods(Beans.java:246)
    at org.jboss.weld.manager.SimpleInjectionTarget.<init>(SimpleInjectionTarget.java:85)
    at org.jboss.weld.manager.BeanManagerImpl.createInjectionTarget(BeanManagerImpl.java:1006)
    at org.switchyard.cdi.ServiceDeployer.addInjectableClientProxyBean(ServiceDeployer.java:86)
