The idea was that you can use

vtkGlobalJavaHash.DeleteAll()

to get all the VTK C++ objects deleted before the program exits. This
is similar to closing open files in C before the program exits; it's
nice but not required. The OS should eliminate all memory used by the
program even if you do not call DeleteAll().

In reality, there are times when DeleteAll() has been found not to
entirely work (i.e. there are still VTK objects around after this
call). So you can choose to use it or not.
