I've got a hard time believing this as well. In very early 1.1 VMs
singleton unloading was a problem but has since been solved. This *might*
be a problem with VMs on Linux. Have you tested on non-Linux VMs?
There was a JDC Tech Tips re: how to get around this for early VMs (I'll see
if I can find it). But basically the solution, like you mentioned, was to
keep a reference to the singleton in a main() somewhere.

The singleton is one the most fundamental OO design patterns. Most of the
books on design patterns talk about this pattern, including the Gang of Four
book.
