    Description

      Non public interface producer

      With the following:

      /* package-private */ interface NonPublicInterface {
}

@Produces
@ApplicationScoped
NonPublicInterface producer() {
}

      With Weld SE, the following exception is thrown:

      Caused by: org.jboss.weld.exceptions.WeldException: WELD-001524: Unable to load proxy class for bean Producer Method [NonPublicInterface] with qualifiers [@Any @Default] declared as [[BackedAnnotatedMethod] @Produces @ApplicationScoped producer()] with class class java.lang.Object using classloader sun.misc.Launcher$AppClassLoader@5ce345c2
Caused by: java.lang.RuntimeException: java.lang.IllegalAccessError: class org.jboss.weld.proxies.NonPublicInterface$1654568476$Proxy$_$$_WeldClientProxy cannot access its superinterface NonPublicInterface
Caused by: java.lang.IllegalAccessError: class org.jboss.weld.proxies.NonPublicInterface$1654568476$Proxy$_$$_WeldClientProxy cannot access its superinterface NonPublicInterface

      For injection points within the same package. Note that works fine with OpenWebBeans.

      Private nested class

      With the following:

      import com.codahale.metrics.MetricRegistry;

@Produces
@ApplicationScoped
MetricRegistry registry = new MetricRegistry();

      With Weld OSGi (in Karaf with PAX CDI) and JDK 7 (HotSpot build 1.7.0_80-b15), the following exception is thrown:

      Because MetricRegistry contains a private nested class.
