Sebb created LANG-806:
-------------------------
Summary: RandomStringUtils can enter infinite loop if chosen char
does not meet letter/digit requirements
Key: LANG-806
URL: https://issues.apache.org/jira/browse/LANG-806
Project: Commons Lang
Issue Type: Bug
Affects Versions: 3.1, 2.6
Reporter: Sebb
Assignee: Sebb
If numbers == true or digits == true, then an infinite loop can result if the
selection process never returns a char that passes the validation test.
This can occur with
RandomStringUtils.random(1, -1, 1, true, true)
because the gap is 2, i.e. random.nextInt(gap) + start == 0
This is trivial to fix; the code should check that start >=0 and end > start
(unless start==end==0).
It can also occur if the provided char array or array subset does not contain
any valid chars.
