RuntimePersistentEntity missing implementation

[viniciuslrangel]

It's missing RuntimePersistentEntity#getCompositeIdentity implementation and respective usages. When there is a jpa @Entity with multiple @Id using the @IdClass, internal runtime mapping fails.

Do a breakpoint at io.micronaut.data.model.runtime.RuntimePersistentEntity.(RuntimePersistentEntity.java:104)

Steps to Reproduce

1. Run a test with a multiple ID JPA entity and schema-generate with create value

Environment Information

• Micronaut Version: 2.0.2
• JDK Version: 11.0.7

• I'm using Kotlin 1.4.10

Example Application

• https://github.com/viniciuslrangel/micronautJpaMultipleKeyIssue ./gradlew test

Stacktrace:

Caused by: io.micronaut.data.exceptions.MappingException: Constructor argument [id2] for type [com.example.jpa.ExampleEntity] must have an associated getter
	at io.micronaut.data.model.runtime.RuntimePersistentEntity.<init>(RuntimePersistentEntity.java:104)
	at io.micronaut.data.model.PersistentEntity.of(PersistentEntity.java:299)

Any update on this? I'm getting the same error.
