UnmarshalException failed to unmarshal interface java.util.List

We have a client application that can be run either thru

Java Web Start or from a main. This problem does not occur when

running from the main method but does occur running from web start.

This is found at the bottom of the stack trace:

Error retrieving Application records java.rmi.UnmarshalException: failed to unmarshal interface java.util.List; nested exception is:

java.io.InvalidClassException: failed to read class descriptor

I might understand this if the interface listed above was either one of our interfaces or

one of our classes, BUT java.util.List?

Suggestions?
