Review comment:
If the padding isn't important and we're okay with ambiguous substring
matches, it could be worth considering simple concatenation to avoid poor
String.format performance until we get something like
[jep-348](https://openjdk.java.net/jeps/348).
```suggestion
this.id = type + "-" + COUNT.getAndIncrement();
```
