can not call overload method

[ywf4026]

when using java.lang.Math.pow(2, 2.5) function, get a javassist.CannotCompileException: [source error] pow(int,double) not found in java.lang.Math

The Class Math doesn't contain function pow(int, double), but contains pow(double,double).
Does javassist not support reload method?

       ClassPool pool = ClassPool.getDefault();
        pool.insertClassPath(new ClassClassPath(JavaasistTest.class));

        CtClass formulaClass = pool.makeClass("A");
        CtClass mapClass;
        try {
            mapClass = pool.get("java.util.Map");
        } catch (NotFoundException e) {
            throw new RuntimeException("Map exception");
        }

        CtMethod runMethod = new CtMethod(CtClass.doubleType, "run", new CtClass[]{mapClass}, formulaClass);
        runMethod.setModifiers(Modifier.PUBLIC);
        try {
            String body = "{double s = Math.pow(2, 2.5);return s;}";
            runMethod.setBody(body);
        } catch (CannotCompileException e) {
            throw new RuntimeException("CannotCompileException1 exception");
        }
