Description

Calling MyEnum.values() works great on the AppEngine local development server, but once this code runs in production you get:

java.lang.IllegalAccessException: Reflection is not allowed on protected native java.lang.Object java.lang.Object.clone() throws java.lang.CloneNotSupportedException

Enum.valueOf(type, value) also fails catastrophically with

java.lang.IllegalArgumentException: MyEnum is not an enum type
at java.lang.Class.enumConstantDirectory(Class.java:2982)
at java.lang.Enum.valueOf(Enum.java:209)

Again, this only happens on the AppEngine production system.

I guess that means, that if we do the clone, then we should do that by using a direct method call instead. If we don't use clone, then this is a AppEngine problem

Moving the enum to src/main/java works, so it is a Groovy issue.
