M. Justin commented on LANG-1254:
---------------------------------
This can be closed as resolved since it was fixed in 3.13.0 per commit [DMI:
Random object created and used only
once|https://github.com/apache/commons-lang/commit/2978cb6cf05379fd42374eb5a235be84e021f247].
[Release 3.13.0 –
2023-07-23|https://commons.apache.org/proper/commons-lang/changes-report.html#a3.13.0]:
> DMI: Random object created and used only once (DMI_RANDOM_USED_ONLY_ONCE);
> Better multi-threaded behavior. Thanks to SpotBugs, Gary Gregory.
> ThreadLocalRandom should be used in utility classes

> I noticed that both {{RandomUtils}} and {{RandomStringUtils}} use a constant
> for the {{Random}} instance. The javadoc for
> [Random|http://docs.oracle.com/javase/8/docs/api/java/util/Random.html]
> indicates that
> [ThreadLocalRandom|http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ThreadLocalRandom.html]
> should be used for performance in multithreaded designs. I would think that
> a public utility class would qualify as a multithreaded design and should
> therefore use {{ThreadLocalRandom}}
