RFR: 8308803: Improve java/util/UUID/UUIDTest.java

Wed May 24 19:26:50 UTC 2023

UUID is very important class that is used to track identities of objects in large scale systems. Yet, the coverage in JDK test is disappointing: it tests only 100 of UUID instances per test, which is way too small to detect collisions due to the bad randomness for example.

I have some pending work to improve UUID performance, and tests should be improved. 

The improved test still runs in less than 5 seconds on my laptop.
