public class Axon4ToAxon5QueryResponseTypes extends org.openrewrite.Recipe
Unwraps Axon Framework 4 ResponseTypes wrappers on AF5-shape (typed-payload, two-argument) J.MethodInvocation calls against QueryGateway.

AF5 dropped the ResponseType SPI: the gateway now accepts a plain Class<R> for single-response queries and exposes a separate queryMany(...) for multi-response queries. For call sites that already pass an object payload — i.e. the AF5 shape queryGateway.query(payload, ResponseTypes.instanceOf(R.class)) — the wrapper can be removed mechanically:

  • query(payload, instanceOf(R.class)) → query(payload, R.class)
  • query(payload, optionalInstanceOf(R.class)) → query(payload, R.class) — the future resolves to null when absent in AF5; behaviour-preserving rewrite.
  • query(payload, multipleInstancesOf(R.class)) → queryMany(payload, R.class) — the only paired method-name change.

Deliberately conservative scope. The recipe never fires on the three-argument AF4 form query(String name, Object payload, ResponseType) — that form has no AF5 overload, and silently rewriting it would (a) produce code that does not compile and (b) destroy the fingerprint that the LLM-driven axon4-to-axon5-querygateway skill needs to recognise the AF4 string-named pattern (so it can introduce typed query message classes). For the same reason the recipe skips subscriptionQuery(...) entirely — even the typed-payload form needs a structural rewrite of the surrounding SubscriptionQueryResult.initialResult/updates/close ceremony, which the skill must drive. streamingQuery(...) already takes a plain Class<R> in AF4, so there is no wrapper to unwrap.

Imports for org.axonframework.messaging.responsetypes.ResponseType and …ResponseTypes (including static …ResponseTypes.*) are removed only after the file has no remaining references to those types — projects that mix the two-argument AF5 shape with still-untouched three-argument AF4 sites keep their imports until the per-construct skill finishes the migration.
