StackOverflowError at AbstractJackson2HttpMessageConverter.resolveVariable [SPR-14520]

[spring-projects-issues]

Gerasimov Gennady opened SPR-14520 and commented

Jackson 2.8.1
Spring 4.3.1.RELEASE

We have a complex hierarchy of classes like

public class Api
        extends BaseApi
        implements CrudApi<ObjectA, ObjectB, Long> {
}

where

public interface CrudApi<S extends BaseSearchFilter<?, ID>, D extends Dto<ID>, ID extends Serializable & Comparable<ID>> extends ReadOnlyApi<S, D, ID> {
}

Applications fails with:
Caused by: java.lang.StackOverflowError: null
at org.springframework.core.ResolvableType.hasGenerics(ResolvableType.java:474)
at org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter.resolveVariable(AbstractJackson2HttpMessageConverter.java:326)
at org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter.resolveVariable(AbstractJackson2HttpMessageConverter.java:332)
at org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter.resolveVariable(AbstractJackson2HttpMessageConverter.java:332)
at org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter.resolveVariable(AbstractJackson2HttpMessageConverter.java:332)
...

The issue is in line 332. At some point the method resolveVariable faces Object as result of contextType.getSuperType() and falls with StackOverflowError as result for getSuperType() method for Object is Object.

I tried to check what if there is a check for that and method continues further. Looks like it works well.

There is a code below which i added to check what happenes if method passes further after line 332

final Class contextTypeSuperType = contextType.getSuperType().resolve();
                if (!(contextTypeSuperType == null || contextTypeSuperType.equals(Object.class))) {
                    resolvedType = resolveVariable(typeVariable, contextType.getSuperType());
                    if (resolvedType.resolve() != null) {
                        return resolvedType;
                    }
                }

I'm not sure that this is a bug, but i do not find any solutions for my case in stackoverflow.com or other similar resources.

Might be worth trying Spring Framework 4.3.2 which contains a minor revision of Jackson type handling... Sébastien Deleuze, could you confirm?

4.3.2 did not help in my case. i've checked it.

I hope attached test can help to reproduce the issue

This issue should be fixed in both master and 4.3.x. Could you please give a try with latest snapshot Gerasimov Gennady?
