> The Hibernate Search engine detects if the elasticsearch backend is on the classpath,
> and if so, adds {{o.h.s.backend.elasticsearch.impl.ElasticsearchBridgeProvider}} to the top of the list of the annotation based bridge providers. 
> When processing an entity with a @DateBridge annotation, it picks the elasticsearch provider to converted from/to {{Date}} objects (since it has priority) which in turn fails with the exception:
> {code}

> This exception happens only when using the infinispan modules, where the elasticsearch backend is added as a dependency; in embedded mode the aforementioned provider is not loaded since the elasticsearch is not on the classpath.
> This current behaviour is not the best for two reasons:
> * When using Wildlfy modules, the elasticsearch backend is marked as optional, but still, it's visible in the classpath and gets loaded
> * If the user is not using the elasticsearch backend, but the jar is on the classpath, elasticsearch date conversion will take precedence over the built-in bridge providers, and it shouldn't
