What steps will reproduce the problem?
1.var t:Type = Type.forName("flash.events.EventDispatcher");
2.compile and run
3.see exception in debug trace
<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
    preinitialize="preinit()"
    layout="absolute"
    minWidth="1024"
    minHeight="768">

    <mx:Script>
        <![CDATA[
            import org.as3commons.reflect.Type;

            private function preinit():void
            {
                var t:Type = Type.forName("flash.events.EventDispatcher");
            }
        ]]>
    </mx:Script>

Ignore this bug.

Just noticed this in org.as3commons.reflect.Type:

                    // As the constructor may throw Errors on null arguments arguments 
                    // surround it with a try/catch block
                    try {
                        org.as3commons.lang.ClassUtils.newInstance(clazz, args);
                    } catch (e:Error) {
                        // Logging is set to debug level as any Error ocurring here shouldn't 
                        // cause any problem to the application
                        logger.debug("Error while instantiating class {0} with null arguments in order
to retrieve constructor argument types: {1}, {2}" +
                                     "\nMessage: {3}" + "\nStack trace: {4}", clazz, e.name, e.errorID,
e.message, e.getStackTrace());
                    }
