A DESCRIPTION OF THE PROBLEM :
--mac-signing-key-user-name no longer works as expected, jpackage complains that it cannot find the cert. This is down to a simple string matching bug.

Now you need to provide a user ID in it too, e.g.: --mac-signing-key-user-name "Company Name (ABC1234567)", for example.

This was never the case before and is contrary to the documentation: "Team or user name portion".

It's down to this buggy code:

        var matchingCertificates = mappedCertficates.stream().filter(e -> {
            return signingIdentityNames.contains(e.getKey());
        }).map(Map.Entry::getValue).toList();

... in SigningIdentitiyBuilder.

This is a regression.

It would also be helpful, please, if you logged the commands you're running and the number of certs found, etc., especially if --verbose is specified. We're completely 100% in the dark about what jpackage is doing. Debugging this stuff is not easy and there are problems from release to release.

REGRESSION : Last worked in version 21.0.9
