Well, it's a little delicate here. Even if we support multi-byte tag one day, this constructor will still only be used to create a single-byte tag `DerValue`, and it's illegal for a single byte tag to end with 0x1f. So the words above is to remind people that they cannot create a tag number 31 `DerValue` just because it seems it still fits into the 5 bits. Precisely, the words should be "this constructor only supports tag number between 0 and 30", but... I'll choose your words. ------------- PR: https://git.openjdk.java.net/jdk/pull/3391
