StackOverflow when constructing an object with Assemble Model

[sofurihafe]

Description

When trying to generate tests for a method that returns an object with cross-reference relationship, StackOverflow exception is thrown.

To Reproduce

1. Generate a test for the following code:

class FirstClass {
    SecondClass secondClass;

    FirstClass(SecondClass second) {
        this.secondClass = second;
    }
}

class SecondClass {
    FirstClass firstClass;

    SecondClass(FirstClass first) {
        this.firstClass = first;
    }
}

public class ClassWithCrossReferenceRelationship {
    public FirstClass returnFirstClass(int value) {
        if (value == 0) {
            return new FirstClass(new SecondClass(null));
        } else {
            FirstClass first = new FirstClass(null);
            first.secondClass = new SecondClass(first);

            return first;
        }
    }
}

Actual behavior

Additional context

Setting useAssembleModelGenerator to false bypasses the problem.
However, it leads to NoSuchFieldException.
