Utils.java:
```
1252 // Normalize state
1253 public static String[] normalizeVersionInfo(String
nimbusKeyVersionInfo) {
1254 String[] normalizeVersionInfo = new String[2];
1255 int lastIndex = nimbusKeyVersionInfo.lastIndexOf("-");
1256 normalizeVersionInfo[0] = nimbusKeyVersionInfo.substring(0,
lastIndex);
1257 normalizeVersionInfo[1] =
nimbusKeyVersionInfo.substring(lastIndex + 1);
1258 return normalizeVersionInfo;
1259 }
```
We should make a class out of BlobVersion, with `name` and `version` as
members. It's easier to understand than a `String[]` value.
