[IO-552] FilenameUtils.concat fails if second argument (fullFilenameToAdd) starts with '~' (tilde)

• Type: Bug
• Status: Open
• Priority: Critical
• Resolution: Unresolved
• Affects Version/s: 2.2, 2.5
• Component/s: Utilities

Environment

Windows 7 64bit, JavaVM 1.8 32bit

Description

FilenameUtils.concat("c:/temp", "~abc.txt") returns "~abc.txt/" instead of "c:/temp/~abc.txt".

As a result, the file would be created in the user's home directory instead of c:/temp.

(Note: I Had to replace all instances of double backslashes that would normally appear in the java code with forward slashes as the editor cannot handle backslashes properly.)

commons io 2.2. and 2.5 behave the same. 2.3 and 2.4 not tested.
