I have just started programming with Objectify in Google app engine. After doing the Objectify setup when I run my code its throwing an exception on the very first statement that registers my entity - "java.lang.NoClassDefFoundError: com.google.common.primitives.Primitives is a restricted class. Please see the Google App Engine developer's guide for more details." What could have gone wrong?

I am using the JRE under OpenJDK 1.7. I have the jar files for Objectify 5.1.13 and Guava copied to the WEB-INF/lib folder of my application. Please find the exception stack-trace below -
