Would it be possible to just remove the jsvc dependencies in future dpkg files for ubuntu installs? I am running JRE 11 with a compiled version of jsvc 1.4.0 and installed the controller using dpkg -i --ignore-depends=jsvc which installs just fine, except it still adds the JSVC dependencies into /var/lib/dpkg/status which means I have to manually edit that file and remove the JSVC dependencies everytime the controller updates, otherwise aptitude yells at me that I have unmet dependencies when I try to upgrade my OS or other software and wont let me go any further unless I install JSVC from the package manager, which will install 1.0.15-8 and then break my controller. It isnt 100% necessary, but still annoying that I have to remember to do it everytime the controller software is updated. 

Just to document how to fix it (in case it helps anyone else)

Once you install with dpkg -i --ignore-depends=jsvc and the omdac 

You need to edit your /var/lib/dpkg/status

sudo nano /var/lib/dpkg/status

Then you can use control w to search for "omadac"

Go down to the Depends line and delete JSVC (>=1.0.8)

Save it and exit... now aptitude wont scream at you and prevent you from using it unless you "fix" the broken dependencies which will install JSVC 1.0.15-8 and break the Omada SDN running Java 11.
