CyclicPropertyReferenceException: Found cycle for field... [DATAMONGO-1255]

Bilguun Bayarmagnai opened DATAMONGO-1255 and commented

Two types of scenarios are printing CyclicPropertyReferenceException log in our application similiar to the https://jira.spring.io/browse/DATAMONGO-962.
We have created tiny demo app using spring boot to illustrate these scenarios.

1. When domain class contains itself(I guess in this case exception makes sense because there's a cycle, but if we can just ignore that.):

@Document
public class Foo {
	@Id
	private String id;
	private Bar bar;
}

public class Bar {
	private Bar previous;
}

2. Next case is tricky. If property class(Partner) contains same field on same name(job) it throws exception. Plus Job class has to have a non-primitive field(Salary) to throw this exception.

@Document
public class Worker {
	@Id
	private String id;
	private Job job;
	private Partner partner;
}

public class Partner {
	private Job job;
}

public class Job {
	private Salary salary;
}

I'm not sure if the case #1 is intentional, but we will keep the structure as it is. But it would be great if this just a bug and can be fixed, or at least there's a way to ignore it. Case #2 can be avoided by naming differently, but still not an ideal solution.

p.s this is not causing serious issues, other than showering our console with ugly exceptions

Affects: 1.6.3 (Evans SR3)
