Description

FilenameUtils#normalizeNoEndSeparator states in the javadoc that :
"A double slash will be merged to a single slash (but UNC names are handled)."

It has been observed that if a double backslash occurs after the colon in a windows filepath, then the returned path still contains this double backslash. For example:

C:\\Program Files\\ExampleDirectory  -->  C:\\Program Files\ExampleDirectory 

While the expectation is that we should be returning ' C:\Program Files\ExampleDirectory '
