Reudismam Rolim de Sousa commented on GIRAPH-1204:
--------------------------------------------------
FileInputStream and FileOutputStream override the finalize method. As a result,
their objects are only cleaned when the garbage collector performs a sweep.
Since Java 7, programmers can use Files.newInputStream and
Files.newOutputStream instead of FileInputStream and FileOutputStream to
improve performance. finalize method is deprecated in Java 9+.
> Avoid FileInputStream and FileOutputStream
