quarkus: Yasson is unable to deserialize an Optional in native

Describe the bug Yasson is unable to deserialize a POJO with an Optional<String> attribute in native mode. There is no issue in JVM mode.

There is no stacktrace, only the following SEVER log:

Expected behavior Deserializing an Optional<String> works in both native and JVM mode.
