-------------------------------------
Summary: isAllUpperCase should only check Alpha characters
Key: LANG-1043
URL: https://issues.apache.org/jira/browse/LANG-1043
Project: Commons Lang
Issue Type: Bug
Components: lang.*
Affects Versions: 3.3.2
Reporter: Frédéric JECKER
Currently, isAllUpperCase checks character by character if the current
character is UpperCase or not using Character.isUpperCase().
The problem is that characters like spaces aren't considered as uppercase
characters.
IMHO, isAllUpperCase should only check the state of alpha characters so that :
- StringUtils.isAllUpperCase("ABC DEF GHI") = true (false currently)
- StringUtils.isAllUpperCase("ABC / DEF") = true (false currently)
