Context

We use Infinispan Protostream annotations to generate marshallers. On Java ≤21, the Protostream annotation processor is auto-discovered from the compile classpath. Starting with Java 22, a dedicated processor path is required.

decision

Define the annotation processor inside the maven maven-compiler-plugin
