以下是自定义函数内容：

package com.fr.function; 

import com.fr.script.AbstractFunction;

/**

public class TranslateToBaidu extends AbstractFunction{

    private static final double x_pi = 3.14159265358979324 * 3000.0 / 180.0;

    private static final double pi = 3.14159265358979324;

    private static final double a = 6378245.0;

    private static final double ee = 0.00669342162296594323;

    public Object run(Object[] args){

        /*获取google地图的经纬度坐标*/

        double lon_lat[] = new double[2];

        String []temp = null;

        temp = args[0].toString().split(",");

        lon_lat[0] = Double.valueOf(temp[0]);

        lon_lat[1] = Double.valueOf(temp[1]);

        double x = lon_lat[0], y = lon_lat[1];

        double z = Math.sqrt(x * x + y * y) + 0.00002 * Math.sin(y * x_pi);

        double theta = Math.atan2(y, x) + 0.000003 * Math.cos(x * x_pi);

        double bd_lon = z * Math.cos(theta) + 0.0065;

        double bd_lat = z * Math.sin(theta) + 0.006;

        String result = String.valueOf(bd_lon)+","+String.valueOf(bd_lat);

        return result;

    }

}

编译不提示成功，日志报这个错误。哪位大神帮看一下哪里出了问题？
