Solution with JAD:

1. Decompile the class with JAD
2. Edit it with your favorite editor
3. Save the file
4. Compile it with javac

More simple solution:

Class<?> c = Class.forName("fully.qualified.name.of.your.Class");
ctor = c.getConstructor(...argument types here...);
ctor.setAccessible(true);

(Your IDE will suggest the type for ctor ... otherwise change it)

Now you can invoke the constructor at runtime.

If you really need to modify the byte code, have a look at the ASM library.
