    Weld 2.1.0 Final fails to create proxies on Swing derived classes

    lstreepy Newbie

      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.

       

      Any suggestions?  Bug?

       

      Thanks,

      Larry.
