After some googling I came upon this website.

Following the (long/first) instructions did solve the problem, and I can now run the application.

Only skipping #9, as I could not find the “CFBundleExecutable”, and simply renaming the old ipscan to ipscan.bak, and renaming JavaApplicationStub to ipscan.
