Thomas BELOT created LANG-805:
---------------------------------
Summary: 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: 2.6, 2.5
Reporter: Thomas BELOT
Priority: Blocker
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 {code}char{code}
array regardless of it's size.
(Besides {code}start{code} is useless here)
Fixed version would be :
{code}ch = chars[random.nextInt(gap)%chars.length];{code}
