Then I'd suggest Java may be ill-suited to your needs.
You may be able to get some level of GC control on a particular
JVM implementation, but it won't be robust. Your control is likely
to slip if you move your Java to another machine, or if you upgrade
the JVM, or even if you do something as innocuous as adjusting the
sizes of assorted memory pools.
For good or ill, Java's "attitude" about garbage collection is
that it's a service provided by the JVM -- in whatever way the JVM
sees fit to provide it, and the JVM is allowed to be capricious.
