    Hot deplyment

      Hi guys,

      I'm development an application using Hot Deplyment strategy, but I found some problems. When I try intercept a method that retuns some value the application performs normal, but when I try intercept a method that returns void occurs an exception.

      protected final void mockMethod(String className, String method, Object obj) throws Exception {
      Class c = sysClassLoader.loadClass(className);
      String expr = "execution(* " + c.getName() + "->" + method + "(..))";

      // checks method integrity
      int methodCount = c.getMethods().length;
      boolean found = false;
      for(int i=0; i < methodCount; i++) {
      Method m = c.getMethods();
      if (m.getName().equals(method)) {
      found = true;
      if (!Modifier.isPublic(m.getModifiers()) && !Modifier.isStatic(m.getModifiers())) {
      return;
      }
      if (m.getReturnType().getName().equals("void")) {
      expr = "execution(public void " + c.getName() + "->" + method + "(..))";
      }
      }
      }
      ...
      }

      As you can see above, I create at runtime the pointcut expression. When method returns void, so I tried to use expression starts with 'call' don't occurs error and 'invoke' method of the interceptor don't fired, but when expression starts with 'execution' occurs NullPointer Exception error.
