SoZry, just noticed right now that this is about a space, not a slash :) ...

File::mkdir will return false, or File::createNewFile will throw IOException if an element in the path has a trailing space. Such pathnames are not legal on Windows. Prior to JDK 25, operations on a File created from such an illegal abstract pathname could appear to succeed when in fact they did not.

Obviously stat() will reliably fail if the path parameter contains a trailing backslash. The backslash is interpreted as an escape character. This will for example cause File_DirExists() to fail. This is of course not the only failure.
