Description

ValueObject A has getB() and ValueObject B has getA(). This is a very common pattern in ORM. Running wsdl2java with -defaultValues=org.apache.cxf.tools.wsdlto.core.RandomValueProvider causes a StackOverflowException in both current release 2.1.2 and 2.2-SNAPSHOT as of 9/23/08. Attached sample project (wsdl and wsdl2java with parameters) reproduces this.
