public class GroovyProxyMetaClassDispatcher
extends java.lang.Object

ByteBuddy delegation target for getMetaClass() on the generated Groovy proxy.

Hibernate assigns the proxy interceptor after the proxy constructor has run, so any intercepted method invoked while the constructor is still executing answers Hibernate's stub value, which is null for getMetaClass(). Groovy trait initializers ($init$) resolve the receiver's metaclass through getMetaClass() from inside the entity constructor and fail with a NullPointerException on that null.

This dispatcher answers the persistent class's MetaClass while the interceptor is not assigned yet - the same answer GroovyProxyInterceptorLogic gives for an uninitialized proxy - and otherwise leaves the proxy's own answer untouched. Mirrors the Hibernate 7 implementation in grails-data-hibernate7.
