ObjectifyFactory.register() does not conform to its contract.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to register the same entity twice using 
ObjectifyService.factory().register(Class)
2.
3.

What is the expected output? What do you see instead?

The Javadoc states: "Attempts to re-register entity classes are ignored.". 
Which is the ideal behavior. However, when I attempt to register an entity a 
second time, an exception is generated:

Caused by: java.lang.IllegalArgumentException: Attempted to register kind 
'Event' twice
    at com.googlecode.objectify.impl.Registrar.register(Registrar.java:82)
    at com.googlecode.objectify.ObjectifyFactory.register(ObjectifyFactory.java:209)

What version of the product are you using? On what operating system?

3.1

Please provide any additional information below.

I do not use DAO (as encouraged by the documentation) nor do I intend to write 
a "warmup" servlet. So I register my Entities with Objectify as needed. If the 
register() method conformed to the contract specified in the Javadoc my code 
would work fine.

You must be looking at the "Current Javadocs" which reflect the code at HEAD 
(Objectify v4).  Objectify4 does in fact ignore duplicate registration 
attempts, but 3.1 throws an exception.

I have added a link to v3.1 javadocs on the home page and updated the current 
link to mention v4.  Sorry about the confusion!
