Major Description
The glob methods in FileContext were copied from FileSystem where they dealt with the a single filesystem.
While they were extended to fit in FileContext they don't seem to deal with URI pathnames correctly.
For example the following two lines in FileContext may be the source of the problem - the scheme and authority seem to be
ignored beyond these points.
line 1013: String filename = pathPattern.toUri().getPath();
line 1035: String filename = pathPattern.toUri().getPath();
