Alexander Smirnov commented on RF-10822:
----------------------------------------

More portable solution is using Serialization for serializable objects - store 
it in the byte buffer and deserialize into copy.

> When user bean implements Clonable interface without overriding clone() 
> method it causes java.lang.CloneNotSupportedException on GAE because of 
> security restrictions. 
> There are 2 ways to resolve this issue:
> 1. let user implement clone() method in her bean and remove 
> AbstractGraphValidator#getCloneMethod(Class<?> clazz) method
> 2. add catch block to the AbstractGraphValidator#getCloneMethod(Class<?> 
> clazz) and throw SecurityException that should be handled by user
