I just "recompile" my .bin file (result of "bsave") using Jess50b2 and
everything works fine. The reported problem was a result of "bload"ing
what was "bsave"ed with previous version.
Is it a problem of the version compatibility? It may create problems
for users with precompiled ruleset (result of "bsave") when they
upgrade. Any suggestion how to avoid this in the future?

Hi,
I'm trying to rebuild my app with just downloaded jess50b2. Before I
had my application built with JDK 1.1.8. At once I decided to try 50b2
and JDK 1.2.2.
Here is an exception I got from application that used to run
bload/bsave without any trouble :
java.io.InvalidClassException: jess.Rete; Local class not compatible:
stream classdesc serialVersionUID=479072369051011645 local class
serialVersionUID=-1625347106253991454

MyClass.init() - Jess reported an error in routine bload while
executing (bload c:/temp/test.bin).
Message: IO Exception.
Program text: ( bload c:/temp/test.bin ) at line 0.
Any idea what is going on?
Thanks,
Alex
