[jira] [Updated] (LANG-1287) RandomStringUtils#random can enter
infinite loop if end parameter is to small
[ https://issues.apache.org/jira/browse/LANG-1287?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pascal Schumacher updated LANG-1287:
------------------------------------
Description:
{quote}I faced that the random method can cause an infinite loop. It can be caused if the end parameter is too low for generating either numbers (< 48) or letters (<65). I added some exception tests to make the cases clear. Basically, if we call the random function with for example numbers = true && end < 48 the validation for Character.isDigit(ch) will fail and we increment count count++.{quote}
