Hi [~james.d.baker], this case should work on master now.
> Yasson compliant Adapter fails with Johnzon
> -------------------------------------------
>
> Key: JOHNZON-309
> URL: https://issues.apache.org/jira/browse/JOHNZON-309
> Project: Johnzon
> Issue Type: Bug
> Components: JSON-B
> Affects Versions: 1.2.3
> Environment: Operating System: Ubuntu 18.04.04
> Java: 11.0.4
> Reporter: James Baker
> Assignee: Romain Manni-Bucau
> Priority: Major
> Fix For: 1.2.5

>
> I have written a simple adapter to allow the serialization and
> deserialization of Java Path objects. The adapter works fine using Yasson
> (which claims to be a reference implementation), but both serialization and
> deserialization fail in Johnzon.
> Serialization results in a StackOverflowError:
> {noformat}
