Sebb commented on LANG-805:
---------------------------
bq. (Besides start is useless here)
I don't think start is useless; it should be possible to specify a subset of
the char array.
> RandomStringUtils.random(count, 0, 0, false, false, universe, random) always
> throws java.lang.ArrayIndexOutOfBoundsException

> Key: LANG-805
> URL: https://issues.apache.org/jira/browse/LANG-805
> Project: Commons Lang
> Issue Type: Bug
> Affects Versions: 2.5, 2.6, 3.1
> Reporter: Thomas BELOT
> Priority: Blocker
> Labels: patch
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> In commons-lang 2.6 line 250 :
> {code}ch = chars[random.nextInt(gap) + start];{code}
> This line of code takes a random int to fetch a char in the _chars_ array
> regardless of its size.
> (Besides _start_ is useless here)
> Fixed version would be :
> {code}ch = chars[random.nextInt(gap)%chars.length];{code}
