If I have a @ProtoField method returning an Object, the processor should log any error saying that java.lang.Object is not marshallable.
Instead, it generates a marshaller for java.lang.Object.
But post-Jigsaw JVMs do not load java.lang classes from application jars, leading to confusing runtime errors like this:
java.lang.NoClassDefFoundError: java/lang/Object$___Marshaller_7cfc5a759c8f8d76ba63b427d975ad253085d80aa05aa8e1121221ae7d5d35cd at org.infinispan.spring.common.provider.PersistenceContextInitializerImpl.registerMarshallers(PersistenceContextInitializerImpl.java:56) at org.infinispan.marshall.protostream.impl.SerializationContextRegistryImpl$MarshallerContext.lambda$update$0(SerializationContextRegistryImpl.java:148) at java.base/java.util.ArrayList.forEach(ArrayList.java:1511) at org.infinispan.marshall.protostream.impl.SerializationContextRegistryImpl$MarshallerContext.update(SerializationContextRegistryImpl.java:146) at org.infinispan.marshall.protostream.impl.SerializationContextRegistryImpl.lambda$addContextInitializer$3(SerializationContextRegistryImpl.java:85) at org.infinispan.marshall.protostream.impl.SerializationContextRegistryImpl.update(SerializationContextRegistryImpl.java:105) at org.infinispan.marshall.protostream.impl.SerializationContextRegistryImpl.addContextInitializer(SerializationContextRegistryImpl.java:85)
I see 2 different problems:
1. java.lang.Object does not have any Protostream annotations, but the annotation processor still creates a marshaller for it.
Creating marshallers for classes without annotations means when compiling a module it's impossible to know which classes in that module will ever have marshallers.
2. Split packages do not work with Jigsaw modules.
Creating a marshaller in the same package but in a different jar is a problem not only for java.lang.Object and java.util collection classes, but also for application classes when using modular jars.
