Thansk for the suggestion, but using BCELified din't help me a lot. I've created
this class

public class Bcelify {

	public static void main(String[] args) {
		
		try {
			JavaClass jclass = new ClassParser("Bcelify.class").parse();
			BCELifier b = new BCELifier(jclass, System.out);
			b.start();
			Class c = int.class;
			System.out.println(c);
		}
		catch(Exception e) {
			System.out.println(e.getMessage());
		}		
	}
}

The instuction I'm interested in is: 
int.class; 
that in the resultin code is generated with 
factory.createFieldAccess("java.lang.Integer", "TYPE", new
ObjectType("java.lang.Class"), Constants.GETSTATIC);

and this is ok. The problem is that if instead of a primitive I use a class name
writing something like String.class I have an "Unknown or invalid constant type
at 42" error. Watching the bytecode the classobject is obtained by a ldc_w
instruction but I don't know how to create it in BCEL casue I've no idea of what
argument I have to pass it.
