This is a bug in 1.1.6 which was fixed in the upcoming 1.1.7
release.

A work-around is to specify the filenames where the public and
private key components shall be written to:

javakey -gk thorsten DSA 512 pub_file priv_file
Generated DSA keys for thorsten (strength: 512).
Saved public key to pub_file.
Saved private key to priv_file.
