What does "IJ.register" method mean?

Hi,
  in the ImageJ's api doc, the class "IJ" has a method "register", and the
api doc says that "Adds the specified class to a Vector to keep it from
being garbage collected, which would cause the classes static fields to be
reset. Probably not needed with Java 1.2 or later."
  May interpret this method in more detail? And in which situation should
one use this method?
  Thanks!
