It seems to me that this renders the InMemPersistenceManager unusable except 
for unit testing (which is works really well for).
None of the properties contain a lot of data - mostly 10 chars or less, in rare 
cases (less than 100 nodes) they would break the 50 character mark and even 
then it's probably maxing out at around 500 characters.  I'm not sure data 
compression would really help.

It looks like there is a great deal of memory overhead with the jackrabbit 
objects because there isn't that much actual data.

I think yes, unfortunately. One idea to solve is to add data
compression to the InMemPersistenceManager. I'm not sure how much that
would save however.
