Bruno P. Kinoshita commented on LANG-1196:
------------------------------------------
>RandomSringUtils is a "utility" class: all methods are static. Passing an
>argument to the constructor will require to remove the static keyword, which
>is not a compatible change.
Ack. Though an alternative could be also include an extra static builder, that
would call a hidden constructor passing a different Random generator.
>Better would be to define a specific interface (as suggested by Jochen on the
>ML).
Agreed :-)
>Even better would be to have a dedicated Commons component (for random-related
>utilities).
I'm lurking there and reading the threads on the RNG spinf off from CM. Waiting
for a few days (or maybe weeks?) vacation to have fun learning prng, rng, etc.
But this would be my favorite option.
Unless this issue gets a pull request, patch, or other suggestions, I'll leave
it as is for now. Thanks Gilles.

> Hi,
> I'm using [Sham
> |http://search.maven.org/#artifactdetails%7Corg.shamdata%7Csham%7C0.3%7Cjar]
> to generate realistic looking test data for both parameterized tests and user
> acceptance testing. We log the seed that is used for each run so that if
> there is an issue we can recreate exactly the same test data. I would also
> like to use some of the commons-lang RandomStringUtils functionality but
> notice that the implementation provides no way of setting the random number
> generator to be used.
> {code}private static final Random RANDOM = new Random();{code}
> A way to configure this would be really useful. If there is an alternative
> way to do this then that would be great. If you think it's a good idea and it
> requires a patch I'm happy to supply one.
> Cheers,
> Gus.
