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

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.
