Hey there.
I just updated from M6 to RAP 1.0. After the update (following the steps
on the RAP homepage), I get the following exception with a formerly
runing project:
17.10.2007 13:34:20 org.mortbay.jetty.servlet.ServletHandler handle
SCHWERWIEGEND: /rap/:
java.lang.NullPointerException

org.eclipse.rwt.internal.lifecycle.RWTLifeCycleThreadPool$Po olWorker.run(RWTLifeCycleThreadPool.java:66)
Any hints? The website only shows up an internal server error (500)
