I have seen this problem as well. We have a Java server application
that scripts the command line so that it can retrieve and accept the
SSL certificate. We added the new --force-interactive option but the
problem is that the prompting seems to happen in the process that
started the Java server application instead of in the application
itself. So it is no longer possible to capture the command line output
with the certificate details and accept it.
Personally, I think this is a regression and not an improvement.
