[jira] [Commented] (IO-783) Fetching file extension using FilenameUtils.getExtension method throws error in windows machine
[ https://issues.apache.org/jira/browse/IO-783?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17720507#comment-17720507 ]
Samraj commented on IO-783:
---------------------------
Verified the code and that was wrong implementation. I have Unix path or EMail path. In that path colon is eligible. When i try to parse that value in windows machine, I am getting error. If I run that code in linux, it is working fine. String parsing should not contain OS check.
