hi all :)

We completed the upgrade from graphql-java 24 to 25-beta5 to take advantage of the new ResponseMapFactory, with something like:
GraphQL.unusualConfiguration(executionInput).responseMapFactory().setFactory(ArrayMapResponseMapFactory.INSTANCE);

In general the upgrade was smooth... we just found a single breaking change in InstrumentationFieldCompleteParameters: the method getFetchedValue was renamed to getFetchedObject.
Maybe it is possible to avoid even that by keep the old method?

Additionally the javadoc for FetchedValue still mention this:
Note: This MAY be returned by InstrumentationFieldCompleteParameters.getFetchedObject() and therefore part of the public despite never used in a method signature.

but perhaps it is not needed anymore as it is annotated with @PublicApi now.

As final feedback, the UnusualConfiguration mechanism is cool and well architected but I was not able to find some nice documentation / blog post about it.

My 2 cents,
D.
