> A user reported on the mailing list a non-serializable exception when using the GlobFIlePathFilters.
> It appears that the PathMatchers are all created as anonymous inner classes and thus contain a reference to the encapsulating, non-serializable FileSystem class.
> We can fix this by moving the Matcher instantiation into filterPath(...).
> {code}

>     final ExecutionEnvironment env =
