Problem with reflection in Generics

Question

I'm using the Prototype compiler for JSR-014 and I am having a big problem with reflection. In the simplest case
class n<T> {
    void go() {
     this.getGenericType().getTypeParameters();
     this.getClass().getGenericInterfaces();
}I get a "cannot resolve symbol" on both lines. A glance at the jar included with the prototype shows why: all the collection classes are there, and a lot of the java.lang types, but not java.lang.Class and none of the java.lang.reflection classes.
So what gives? Is reflection not supported yet? (gaak!) Is there another jar I am supposed to download?
Thanks

Schapel is right.
but also
The signatures for fields and methods will include the generic types.
If you really wanted to, this would work.
get the Class's ClassLoader,
work out the name of the Class's file, and get an inputStream to this resource (from the classloader). (This bit works because I use as a diagnostics tool to see if classes are loaded from my jar, or my patches directory - see below).
Write some stuff to read the class file and parse out the generic signatures for the things you are interested in.
I don't think this last part would fit into anyones definition of "fun", however the specs are all available, and it may turn out simpler than at first appearances.
Here's the code I use to get the location of where a class is loaded from.
    static URL getLoadPath(Class theClass) {
        StringBuffer resourcename = new StringBuffer(theClass.getName());
        for(int i=0;i < resourcename.length(); i++) {
            if(resourcename.charAt(i) == '.') {
                resourcename.setCharAt(i,'/');
        resourcename.append(".class");
        return theClass.getClassLoader().getResource(resourcename.toString());
    }if you use getResourceAsStream() in place of getResource() you will have the .class file as an inputStream which you can read and parse.
