Are you sure you could use 'call'?
because I see the demo of call is
// The methods in this class are called from the CallJavaDemo
// macro at <http://rsb.info.nih.gov/ij/macros/CallJavaDemo.txt>.
// This class can be compiled with ImageJ's
//  Plugins>Compile and Run command.

public class CallDemo {

        public static String method0() {
                return "method0";
        }

        public static String method1(String arg1) {
                return "method1"+"("+arg1+")";
        }

        public static String method2(String arg1, String arg2) {
                return "method2"+"("+arg1+", "+arg2+")";
        }

}
so it just return a string. I do  not know it can work like it.
I just used ' call ' to return the version of ImageJ.
you can change the plugin parametre in the program and then just run it if
you not always change your parameter.
