code: public static MethodCallExpression applyDefaultMethodTarget(final MethodCallExpression methodCallExpression, final ClassNode targetClassNode) {
          return applyMethodTarget(methodCallExpression, targetClassNode, (ClassNode[])null);
      }
docs: Set the method target of a MethodCallExpression to the first matching method with same number of arguments.
  This doesn't check argument types.
