Changeset 1168 for trunk/server/fedora

Make Java work again by reducing its maximum heap size.

Otherwise, it will crash with an out-of-memory error on startup
because it tries to allocate 1.05 G. While one option is to increase
our memory limits, a better one is to make it grab less RAM. The
startup code's idea of "a reasonable fraction" of total physical
memory in the machine is not our idea of a reasonable amount for one
process on scripts to use.
