Review Comment:
While we are at it, it seems `JDK_CLASS_TEST` elements are nicely ordered
alphabetically (aren't they?).
Maybe we want to check if `referee.compareTo(JDK_CLASS_TEST[i]) > 0` and
`return false`? We'll have more slow iterations on the loop, but we can avoid
iterating over all elements. What would the flamegraphs then?
