Be sure to read up on GC if you get a chance. :)  JVMs don't really seem 
to do some of the more advanced techniques yet.

Some fairly good starting points:

ftp://ftp.cs.utexas.edu/pub/garbage/
http://iecc.com/gclist/GC-faq.html
http://www.xanalys.com/software_tools/mm/

Personally, I think GC is a great technique to employ within a 
long-lived application like a MUD server.  I don't think I'd want to 
rely on any of the JVMs that I've seen to date though for that.

For some work that was done on persistence in Java, you might find Sun's 
Forest project of interest: http://www.sun.com/research/forest/
