Ubuntu activation fails

I'm attempting to install the commercial AS2 engine on Ubuntu 16.04 with the OpenJDK 11.

Unfortunately, every activation key fails when attempting to start the service with a "SEVERE: Activation with found activation key(s) failed: key(s) do not match.".

Has anyone installed this on Ubuntu 16.04 and run into this issue?

Anything I should try?

Mendelson apparently doesn't have the knowledge to help me.
