Hi Chihiro, et.al.,
Thanks for taking a look at this issue, however...
There has been a long history of concerns[1] about breaking existing
applications
that depend on the loose parsing of UUIDs. Throwing an exception
where it did not
previously is an incompatible change.
The crucial concern about performance parsing conforming strings has
been addressed by:
8196334 Optimize UUID#fromString
<https://bugs.openjdk.java.net/browse/JDK-8196334>
I propose to close these as WILL-NOT-FIX: and hope that the next
several times it gets reported
they will be closed as duplicates.
8216407 <https://bugs.openjdk.java.net/browse/JDK-8216407>
java.util.UUID.fromString accepts input that does not match expected
format
8165199
<https://bugs.openjdk.java.net/browse/JDK-8165199>UUID.fromString
accepts wrong placements of the dashes
As you say, any tightening up of the validation after 15+ years will
create a potential compatibility issue and might not be worth it. Maybe
we could re-purpose JDK-8216407 to clarifying the javadoc instead? That
would at least help with these bug reports when people are surprise that
fromString doesn't fail.
