Sorry, but I'm at a loss to explain why simple.java should be generating a
ClassCastException. I've tried with JDK 1.3 as well and it seemed OK. All
InstantDB does is serialize the object to a byte array and then save that to
disk. It then does the reverse to retrieve it.

Any serialization experts out there who could hazard a guess at the possible
source of the problem? Anyone seen anything similar?

Sorry - not at the moment.
