我已从 4.0 更新到 Glassfish 4.1，现在无法从 JConsole 和 VisualVM 访问它（但我以前可以）。JConsole 在输入用户/密码之前输出以下内容：

Glassfish 的日志中有这样一行：
JMXStartupService has started JMXConnector on JMXService URL service:jmx:rmi://Debian-70-wheezy-64-minimal:8686/jndi/rmi://Debian-70-wheezy-64-minimal:8686/jmxrmi
我可以使用 telnet 连接。我该如何解决这个问题？
