在数组中添加更多元素时出现问题

Question

我正在尝试使用jcraft将json对象从java窗口发送到Unix。当数组大小为65时，它工作正常但是当我添加一个数组元素时，它会抛出com.jcraft.jsch.JSchException引起：java.lang.ArrayIndexOutOfBoundsException。 关注方法如下： -

public void appendData(String user, String pwd, String host, Integer port,
            String str_Content, String usrHome, String destDir, String fileName) {
        int statusCode = -5; 
        try {
            java.util.Properties config = new java.util.Properties();
            config.put("StrictHostKeyChecking", "no");
            JSch jsch = new JSch();
            Session session = jsch.getSession(user, host, port);
            session.setPassword(pwd);

            session.setConfig(config);
            session.connect();
            System.err.println("Connected");
            Channel channel = session.openChannel("exec");

            ((ChannelExec) channel).setCommand("echo " + "\'" + str_Content
                    + "\'" + " >> " + usrHome + destDir + "/" + fileName);

            channel.connect();// ---------This line gives error -------
            channel.disconnect();
            session.disconnect();
            System.out.println("Waiting for next hit...");
        }
        catch (JSchException e) {
            e.printStackTrace();

        }

    }// appendData

堆栈跟踪是： -
