I've added TypeInfo::isInstance(Object) to JBoss Reflect, so check if it is already available when you implement this: | if (componentType != null) | { | TypeInfoFactory tif = componentType.getTypeInfoFactory(); | TypeInfo childTypeInfo = tif.getTypeInfo(child.getClass()); | if (componentType.isAssignableFrom(childTypeInfo) == false) | throw new IllegalArgumentException("Illegal child type"); | } | vs. | if (componentType != null && componentType.isInstance(child) == false) | { | throw new IllegalArgumentException("Illegal child type"); | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4192006#...
