Okay I will try answering my own question:
It turned out, that with my configuration (Windows Server 2019 and Adopt
OpenJDK 11) I needed to specify an additional argument to make the
localhost JMX connection work.
This is the complete list of arguments used for the JMX server:
-Dcom.sun.management.jmxremote.port=9011
-Dcom.sun.management.jmxremote.host=localhost
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=localhost
With the additional last parameter it worked as before. So this has
nothing to do with the initial question.
Btw: --add-modules is used in jlink to create a custom image so I was
complete out of scope with that.
Kind regards

Hello,
I am trying to run my service with procrun as usual. After migration
to JDK11 I found out, that a connection with jconsole (JMX) is no
longer possible although the arguments for the JVM are the same as
before. After some investigation I found out, I have to explicitly
load the module jdk.management.agent. So I am trying to somewhere get
the --add-modules jdk.management.agent part into the service config.
But I have had no success so far. Adding it to the standard JvmOptions
pane fails with:

Is this at all possible or do I have a fundamental misunderstanding of
the issue?
