I have an entity that has uses converter

@Column(name = "STATE_ID")
@Convert(converter = StateConverter.class)
private State state;

When I use hibernate-core-5.4.14-SNAPSHOT.jar everything works fine and there is no any exceptions. However, when I tried to use hibernate-core-6.0.0.Alpha4.jar I get the following:
