Mas é impossível ter uma conexão com a visual vm.
No add jmx connection tentei com
1.2.3.4:7001
1.2.3.4:8888
com e sem credenciais. Mas sempre o mesmo resultado: cannot connect to ...

Usando localhost:8888 , não está funcionando.
Remotamente, jmap -permstat 1.2.3.4:888 me dá
Attaching to remote server 1.2.3.4:8888, please wait...
