Java equivalents to dbm/gdbm libraries?

I'm working on a project for which I want to use a Java library which lets me treat an on-disk file as a very large HashMap--basically, the equivalent of what dbm/gdbm can do in C, as typified by Python's 'pickle' module. There is already quite a nice BSD license Java library call JDBM which does this; it allows either keys or data to be arbitrary objects, and seems to be quite stable (in spite of its version number being 0.12). However, before I use that, I thought I would check to see if anyone could recommend other similar libraries which might be more advanced or use more recent technology. (JDBM, for example, dates from the era when Enumerators rather than Iterators were the way to go :-) ).

This sort of functionality can be incredibly useful, and I'm very surprised Sun hasn't included anything like it in the standard distribution.

Thanks,
Ken McDonald
