The application works fine in Eclipse.
In Eclipse, I created a jar file x.jar from the .class and a few .drl files, and copied x.jar to /tmp/x/
Now, in /tmp/x
CP="droos/*:drools/lib/*"
java -cp "$CP" -jar dpvt.jar par...
This fails on the first attempt to access any class from a drools jar file.
In /tmp/x, I unpack x.jar and call
CP="droos/*:drools/lib/*:."
java -cp "$CP" rss.aws.init.Main par...
AND THIS WORKS!
So, what is different when starting a Java program with java -jar as opposed
to java x.y.Main?
The stack dump is not very informative:

Any ideas?
