Java Mission Control 7 running on Java 11 cannot connect to Wildfly with "jmx:remoting-jmx" protocol

As far as I can tell, I am having the same issue described here:
https://developer.jboss.org/thread/278895
(That forum is closed and no additional comments are allowed, their recommendation is to post to SO)
I am trying to run JMC 7.1.2 on OpenJDK 64-Bit Server VM Corretto-11.0.8.10.1 (build 11.0.8+10-LTS, mixed mode) on my workstation and connect to a remote Wildfly server using the "jmx:remoting-jmx" protocol. This worked for years, but AFAICT does not work in the constellation Java-11 and JMC7.
There is no error about unknown protocol or similar
(Yes, I have already read and followed instructions in:
Connect Java Mission Control to Wildfly 16), but I get this error when connecting:

If I use OpenJDK 8 with JMC 7 then it works (that is, I can connect and also read jfr files created with jdk11) but is that really the only way to get this configuration to work?

I am passing all the right arguments according to the oracle docs.

then why i am getting this error.
thanks in advance.

Intellij can't run Wildfly server

I'm trying to get Intellij IDEA to work with a Wildfly 10 server. I installed Intellij following this and Wildfly thanks to this script.
The startup script used by Intellij is /opt/wildfly-10.0.0.Final/bin/standalone.sh, which I tried to run manually, and I got the following error :

This is exactly the same I get as output in Intellij.
I found thanks to this topic that it may be a matter of user permissions.
However, when I try to add a user to wildfly with the add-user.sh script, I get this error : ./add-user.sh: 1: eval: /usr/lib/jvm/jdk1.8.0_60/bin/java: not found
It is looking for a wrong JDK path. I tried to change it following different solutions but none of them work.
My JAVA_HOME is set to /usr/lib/jvm/java-8-oracle .
Is any of you having an idea of what to do ? Thank you in advance :)

Forget the add-user.sh script. This is for adding users to wildfly. Your issue is with your Linux users.
The directory has to be writable by whatever user wildfly is running as.
If you are running it as a user named wildfly then you have to change the ownership of those directories to that user. According to your question it looks like you are running as some other user that does not have permissions to those directories.
If you want a quick easy fix and you aren't worried about other users on the system you could just change permissions like:
sudo chmod -R 766 /opt/wildfly/standalone/
This will give the owner all permissions, and other users read/write permissions to those directories.
This is not best practice. Best practice is to give that directory ownership to user 'wildfly' with permissions of 600. Then you should run wildfly as the 'wildfly' user on linux. Any startup script you can find will likely do this for you.

I followed the technote https://www-304.ibm.com/support/docview.wss?uid=swg21515079 - "An exception occurs on 64-bit WebSphere servers when running reports from ClearQuest data sources that require the Java Native Interface (JNI).
As suggested, WAS 32-bit was installed instead on 64 bit. But the error still occurs. Can you please let me know where this library is or what is going wrong?
Thanks,
Aarthi

The ClearQuest libraries and jars need to be placed on the path so WebSphere can pick them up. Did you source cq_setup.csh prior to starting the WebSphere profile? You would need to source cq_setup.csh and then start the profile in the same shell.

I'm trying using my local user, root user, changing ports (ie: run 8080), start instead of run, and it always throw the same exception.
By the way, port 9000 is not in use by another application.
Anyone has any clue?
I'm using Ubuntu 12.04 LTS, and Play Framework 2.2.6.
Thanks.

The error is that your port is being used by another process.
In a UNIX machine the command lsof -i:9000 will give the processes that are using the port.
As you have noted correctly processes with root permissions can be hidden if you use the terminal not as root
