Turn off the use of memory mapping on the file channel; it is one of those connection paraemters options as I recall; also using new ShapefileDataStore is not that cool in a production application - try to use the DataStoreFinder so you can take advantage of improvements to our code as you update GeoTools.
Also please build and try out trunk; it has a new implementation of Shapefile for your testing pleasure. Jody > run your program with more heap space ?
