I stumbled upon a Javassist problem, when it fails to add code with insertBefore().

If someone can help, I would really appreciate this.

package test;
public class TheAddress extends TheModel {
 static{
 foo("The address!!!");
 }
}

package test;
public class TheModel {
 public static void foo(String param){
 System.out.println("Inside foo, param: " + param);
 }
}

package test;
import javassist.*;
public class JavassistTest {

 public static void main(String[] args) throws Exception {

 ClassPool pool = ClassPool.getDefault();
 CtClass clazz = pool.get("test.TheAddress");
 CtMethod foo = getMethod("foo", clazz);

 foo.insertBefore("{ System.out.println(\"inserted before foo!\");}");

 clazz.writeFile();
 clazz.toClass().newInstance();
 }

 static CtMethod getMethod(String name, CtClass target){
 for (CtMethod method : target.getMethods()) {
 if (name.equals(method.getName())) return method;
 }
 return null;
 }
}
