> {{LocalJobRunner#getLocalTaskDir}} creates a directory that is unique to the task ID.  The logic of this method concatenates the local job dir and a task-specific path, but one of the arguments is a {{Path}} with a scheme, so the final result has "file:" embedded in it.  This works on Linux, but the ':' is an invalid character in a file name on Windows.
