输入指令没反应

[CCYYT]

您好，非常感谢您的开源，我在执行时遇到了：
$ ./javadebug-client-launch.sh

   java-debug-console usage:
   javadebug-console-launch.sh [ip:port]

   ip:port : the target jvm host info, optional

   example:
      ./javadebug-console-launch.sh 127.0.0.1:11234

start to connect to remote jvm tcp server :
init client logger ...
[error] [Fri May 30 10:53:06 CST 2025] [main] get the ip and port, start to connect remote server:127.0.0.1:11234

127.0.0.1:11234>fc -class java.lang.String

输入指令后，一直没有返回结果，请问我该怎么解决这个问题呢。非常感谢！
