Re: RFR:8207048: jhsdb debugd cannot specify a port number
Hi David and all, My goal is we can set the port of RMI and RMI registry through command line option in jhsdb debugd. So I want to create a CSR request of JDK-8207048 which propose to change jhsdb command line option. P.S.: I have never created a CSR request before. I'll need some time to learn that.

Hi David, Thank you for comment and updating JBS. I'll create a CSR request after getting comments whether this change is welcomed by community.

Re: RFR:8207048: jhsdb debugd cannot specify a port number
Hi Yuji, I can't comment on the actual change proposed in this enhancement request, but it will need to have a CSR request created and approved due to the use of a new system property.
