This is a bug in 1.1.6, which has been fixed in 1.1.7,
which you should upgrade to.

A work-around is to specify the filenames where the public and
private key components of the generated keypair should be stored,
as in:

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