keytool not working properly with Swedish locale

Keytool is not working properly with Swedish locale. This seems related
to bug 4668277, which claims to have fixed both the keytool locale for
French and Swedish. In the latest JRE, keytool is working fine for
French but there is still problems with the Swedish one. The problem
seems to be with the lines in Resource_sv.java that contains the keyword
"datum". It should probably be "date" instead.

Licensee in Sweden was using keytool on a keystore with 5 entries and
tried to list them with:

   keytool -list -keystore testKeystore -storepass keystorepw

and they get:

   Keystore-typ: jks
   Keystore-leverantör: SUN

   Din keystore innehÃ¥ller 5 poster

   nyckelverktygsfel: java.lang.IllegalArgumentException: unknown format
