In JDK-8342062, this change was made in jarsigner resources:

- {"key.bit.weak", "%d-bit key (weak)"},
+ {"key.bit.weak", "%s key (weak)"},

Note that the key is unchanged but the printf modifier inside the value is changed from %d to %s. The caller is now providing a string argument, however, for those non-English resources that have not beed localized yet, an error will report "%d cannot be used with a string".

We should have introduced new resource keys instead of reusing the old ones.
