Hi,
IIOB is invalid to throw here, so I'll fix that. NumberFormatException
is a IllegalArgumentException, so I think it's a gray area if the dash4
+ 1 < name.length()-check is needed.
I sincerely hope keeping error messages as-is isn't required, though.

Hi Claes,
Invalid inputs to UUID.fromString() behave a little different than
before. IllegalArgumentException is not thrown for the following inputs:
For example:
"0": IllegalArgumentException: Invalid UUID string: 0 (before patch)
"0": IndexOutOfBoundsException (after patch)
"-0": IllegalArgumentException: Invalid UUID string: -0 (before patch)
"-0": NumberFormatException (after patch)
"0-0-0-0-": IllegalArgumentException: Invalid UUID string: 0-0-0-0-
(before patch)
"0-0-0-0-": NumberFormatException (after patch)
The following input (and similar) do throw NumberFormatException as
before, but messages are a little different. That's OK, I suppose.
"0-0-0-x-0": NumberFormatException: For input string: "x" (before patch)
"0-0-0-x-0": NumberFormatException: Error at index 1 in: "x" (after patch)
"0-0-0--0": NumberFormatException: For input string: "" (before patch)
"0-0-0--0": NumberFormatException: (after patch)
The 1st 3 examples could be fixed by checking that dash1,2,3,4 are all
> 0 and that dash4 + 1 < name.length()
Regards, Peter

This looks just beautiful!
Thanks!
But why do you need the digits() function at all?
In my opinion, using formatUnsignedLong directly would be no less
clearer.
Sure!

Small improvement with client compiler; no measurable change with
tiered.

Hi,
after recent changes, this patch has been revisited and improved
slightly, primarily simplifying and speeding up the toString method
slightly more:
