> Specification for java.beans package says that:
> "Unless explicitly stated, null values or empty Strings are not valid parameters for the methods in this package. You may expect to see exceptions if these parameters are used." 
> However specification does not explicitly states that NPE should be thrown, RI throws NPE if ava.beans.DefaultPersistenceDelegate.mutatesTo() called with null parameters.
