Runtime Error with Generic & RuntimeSchema

[GoogleCodeExporter]

-- What steps will reproduce the problem? --
1.
Run the attached. When schemaA is defined as in the comment, both schemaA and 
schemaB fail with a nasty java.lang.StackOverflowError.

-- What is the expected output? What do you see instead? --
Prints the object if schemaA = null, else 

Exception in thread "main" java.lang.StackOverflowError
    at com.dyuproject.protostuff.StringSerializer.writeUTF8VarDelimited(StringSerializer.java:743)

...

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

Win XP SP3, protostuff-api-1.0.0

-- Please provide any additional information below. --

Not sure if this is just my ugly code or this case can and should be addressed. 
It did happen to me in a legitimate application code :P

From the email exchange:

Its looking like a race condition on classloading.
When the object was instantiated, the runtime schema started inspecting the 
inner generic object field without it being 
fully loaded.
That's my guess at least.
When its fully loaded, protostuff-runtime used RuntimeObjectField for the inner 
message.
When not, protostuff-runtime used a RuntimeDerivativeField. (there were 
DerivativeSchema printlns from the stackoverflow).

I had the same problem, but it was because of a loop in my object graph (a 
child class held a reference to the parent). Removing this loop got ride of the 
stackoverflow error for me. You might want to double-check the structure of 
your object graph.
