Description polrtex 2007-04-17 20:14:37 UTC 
Trying to replace a reference to an implementing class with a reference to the
interface that the class implements (e.g. Foo implements FooI)

mapclass javaapplication4.Foo => javaapplication4.FooI;

The query starts running, and then blows up with the following exception:

java.lang.NullPointerException

The old Jackpot module is no longer maintained. There is a rewrite in progress at: http://bitbucket.org/jlahoda/jackpot30/wiki/Home
