You can disable the generators' result caching by setting
the gwt.disableGeneratorResultCaching system property.
It's strange though that you have this NPE to begin with. Could you try
running DevMode with "-ea" (in the JVM options) and/or "-logLevel DEBUG"
(in the program args) and see there's something interesting in the output?
