SerializationRegistry and addReflections moved in GraalVM 21.3-dev
Browse files Browse the repository at this point in the history
oracle/graal#3050 introduces a number of changes
around the internal APIs that are being used by Quarkus to register
classes for serialization thus breaking serialization support when using
21.3-dev

These changes are:

1. `SerializationRegistry` class has been moved from
   `com.oracle.svm.core.jdk.serialize` to
   `com.oracle.svm.reflect.serialize`

2. `addReflections` method moved from
   `com.oracle.svm.reflect.serialize.hosted.SerializationFeature` to
   `com.oracle.svm.reflect.serialize.hosted.SerializationBuilder` and
   became `private`

oracle/graal#3050 also introduces
`SerializationFeature.register(Class<?>... classes)` which is available
as a public API (not internal) and can save us from having to keep up
with the internal APIs as new releases come out. This PR leverages the
new API to register classes for serialization when using GraalVM/Mandrel
>=21.3.

Closes #19338
