> sling-mocks: Make compatible when Johnzon is managed to version 1.1
> -------------------------------------------------------------------

> Key: SLING-8061
> URL: https://issues.apache.org/jira/browse/SLING-8061
> Project: Sling
> Issue Type: Improvement
> Components: Testing
> Affects Versions: Testing Sling Mock 2.3.4
> Reporter: Konrad Windszus
> Assignee: Stefan Seifert
> Priority: Major
> Fix For: Testing Sling Mock 2.3.6
>
>
> Whenever sling-mock is used where {{johnzon-core}} is managed from 1.0.0 to
> 1.1.0 the following exception is thrown when executing tests which leverage
> {{SlingContext.load().json(...)}}
> {code}
> [ERROR] testXYZ(my.package) Time elapsed: 0.018 s <<< ERROR!

> The reason is that Johnzon 1.1 implements JSON-P 1.1 and therefore references
> interfaces from the newer spec (e.g. in
> https://github.com/apache/johnzon/blob/b2d205738c65fb53e768fca445fa611515417c19/johnzon-core/src/main/java/org/apache/johnzon/core/JsonProviderImpl.java#L38),
> which are not contained in JSON-P 1.0. Unfortunately the version of JSON-P
> cannot be overwritten by {{DependencyManagement}} as the GAV differs between
> JSON-P 1.0 ({{org.apache.geronimo.specs:geronimo-json_1.0_spec}}) and JSON-P
> 1.1 ({{org.apache.geronimo.specs:geronimo-json_1.1_spec}}).
> An easy fix for this is to load the dependencies for both JSON-P 1.1 instead
> from within sling-mocks, that way it is compatible with both Johnzon-Core 1.0
> and 1.1. (JSON-P 1.1 should be backwards-compatible, so works with both
> Johnzon-Core 1.0 and 1.1).
