-server sets some jvm defaults to values that are more appropriate on a
  server, the actual values it sets varies based on platform (x86, sparc,
  etc)

-Xmx1500m sets the maximum java heap to 1500MB

The java heap is divided into generations so that things that haven't
been garbage collected after a certain amount of time are checked less
frequently.  The MaxNewSize and MaxPermSize options modify the size of
those generations.
