Apparently, the issue has something to do with VisualVM proxy settings.
When I switched the connection method to "direct", all connection issues were immediately resolved. Yet, I'm curious why VisualVM tries to use any proxies when connecting to 127.0.0.1 and/or attaching to a PID.
So, to reproduce the issue, one might set the proxy host to some nonexistent address, and add 127.0.0.1 to non-proxy hosts.
Describe the bug
I'm running the latest released VisualVM version (2.1.0) and Java 17. On Linux, I can't connect to a local process by either attaching to its PID or via JMX. At the same time, it's fully possible to do the same using JConsole or JMC (see the screenshots below).
To Reproduce Steps to reproduce the behavior:
SwingSet2.jar
demo application shipped with the JDK, with JMX agent explicitly enabled:-Djava.net.preferIPv4Stack=true
-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.port=2048
-Dcom.sun.management.jmxremote.rmi.port=2048
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
127.0.0.1:2048
via JMX. The operation succeeds.Expected behavior VisualVM should be able to attach to a JVM process.
