Interceptor creation fails when applied to a method on a class that extends JPanel (probably any swing component)

    Details

      Description

      I'm trying to use weld SE in a standard desktop app, and I've created a couple of Interceptors to ensure that certain methods are called on the EDT.

      An example of one of my annotations:

      @InterceptorBinding
      @Target(

      {ElementType.METHOD, ElementType.TYPE}

      )
      @Retention(RetentionPolicy.RUNTIME)
      public @interface InvokeOnEDT
      {
      }

      And the actual interceptor:

      @InvokeOnEDT
      @Interceptor
      @Priority(1)
      public class InvokeOnEDTInterceptor
      {
      private static final Logger logger = Logger.getLogger(InvokeOnEDTInterceptor.class);

      @AroundInvoke
      public Object ensureOnEDT(InvocationContext ctx) throws Exception

      { logger.warn("INV intercepted: " + ctx); return ctx.proceed(); }

      }

      When I try to initialize the weld container, I get the following exception on any class that uses this annotation on a method and extends a swing component (JPanel is the primary offender):

      This happens on any class that derives from something like JPanel. This seems like a bug to me, but I found almost nothing googling for this except some several year old posts about spring AOP.
