Jconsole 远程连接丢失：重新连接？

Question

I'm trying to make a jconsole remote monitoring of my tomcat 9 with java 8 jre (server adress: 192.168.10.3). In tomcat9w i have this java options:

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=5000
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.local.only=false
-Djava.rmi.server.hostname=192.168.10.3

Firewall is off.

Jconsole with -debug shows me this:

So i can't tell what's wrong with my tomcat and java. I read the tomcat documentation and found nothing there to help me solve this problem.

Answer 1

In my case I tried to run JConsole from openjdk-1.14 against a VM on openjdk-1.11 and got the same error.

Using a different JDK did the trick.
