JsonProviderImpl not found but only for UpdateByQuery responses

I'm getting the following error only when deserialising UpdateByQuery responses:

2023-06-27 18:00:18:193 +0000 [http-nio-8080-exec-4] ERROR Error: Provider org.glassfish.json.JsonProviderImpl not found

Everything else works and has been working for ages.

I'm using this version of the client: co.elastic.clients:elasticsearch-java:7.16.2 running against elasticsearch in docker with container version: docker.elastic.co/elasticsearch/elasticsearch:7.16.2

What could be the problem here?

In case the solution helps anyone else:

The issue was how I was calling the update by query.

All the code is in a springboot application. The code making the call was in a function in a @Component. The function was being called from a @RestController within a java parallelStream. When I changed it back to a stream it was fine.

Something about running the code in a ForkJoinPool means that, for some reason, no JsonProviderImpl is available in the execution context.

It's still a bit of a mystery to me, tbh. But the "fix" was to move from parallelStream back to stream.
