The toString() in openjdk looks like this: | public String toString() { | StringBuilder sb = new StringBuilder(); | | if (ownerType != null) { | if (ownerType instanceof Class) | sb.append(((Class)ownerType).getName()); | else | sb.append(ownerType.toString()); // HERE! | | sb.append("."); | | if (ownerType instanceof ParameterizedTypeImpl) { | // Find simple name of nested type by removing the | // shared prefix with owner. | sb.append(rawType.getName().replace( ((ParameterizedTypeImpl)ownerType).rawType.getName() + "$", | "")); | } else | sb.append(rawType.getName()); | } else | sb.append(rawType.getName()); | | if (actualTypeArguments != null && | actualTypeArguments.length > 0) { | sb.append("<"); | boolean first = true; | for(Type t: actualTypeArguments) { | if (!first) | sb.append(", "); | if (t instanceof Class) | sb.append(((Class)t).getName()); | else | sb.append(t.toString()); // HERE! | first = false; | } | sb.append(">"); | } | | return sb.toString(); | But note the the code I've marked HERE! which in turn would also need fixing if we assume these reflective objects don't have valid toString()s View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4190901#...
