The patch will then need a few adjustments but the principal idea should still work. Cheers, Markus signature.asc Description: OpenPGP digital signature

Dear Markus, Thanks for looking at the problem and finding the fix. I had somehow missed the initial report. I was planning on packaging the latest release.

Please find attached a patch that fixes the issue. The recent update of
libcommons-cli-java to version 1.3.1 introduced some changes in
OptionsBuilder.java which caused this FreeCol runtime error. In general
Freecol should move away from OptionsBuilder because this class is
deprecated. I changed the type from File to Class, and so far the game
works again.
Markus
