Hi Mandy,Alan,
Thanks for your inputs.
If I keep it as launcher option, it may need to know JMX agent flags
which may need to be extended in future.
I would prefer making it a VM option. I will make the required changes
and send out an updated webrev.

Hi Harsha,
JEP 293 [1] describes the guidelines for JDK command-line options. As
Alan points out, new options should move away from -X prefix but use
`--` GNU-style long form option. The guideline says:
The use of |-X| as a prefix to indicate "non-standard" options will be
discontinued for new options, although command-line help may continue
to draw a distinction between more commonly used options and those for
advanced use.
You can consider `--management` as an alternative. Should this be a
launcher option that converts it to the corresponding
`-Dcom.sun.management.jmxremote.<xxx>` rather than a VM option?

Hi Erik,
The minimal command line would be,
"-Xmanagement", that will start only the local management server.
"-Xmanagement:local=true,port=aaaa" will start the remote management
server without SSL or authentication.

Hi Harsha,
Very nice to see progress on this!
Before reviewing, the minimal command line to start up the default
management server now becomes
-Xmanagement:ssl=false,authenticate=false
No. Please refer above for minimal options.
and if you use a property that doesn't exist, or that is mandatory,
you will get an error message stating what is wrong?
If we use property, that doesn't exist, we get invalid option error.
As said before, no options are mandatory.
/<log>//
//./java
-Xmanagement:ssl=true,authenticate=false,rmiregistry_ssl=true
HelloWorld//
//Error: Invalid option specified: rmiregistry_ssl//
//</log>/
Could we reduce the command line further, so only a single property
is needed:
-Xmanagement:secure=false
or perhaps:
-Xmanagement:unsecure
which would set ssl=false,authenticate=false, because that is what
you want 99% of the time.
Thanks
Erik
