Subject: [PATCH] Fixed NPE when using nested classes in entities with
 @EmbeddedId/@Embeddable

Patch supplied by Eduard Szente <eduard.szente@gmail.com>

Details:
----------------
Hi,

when using your plugin for schema export the presence of nested classes
in entities (e.g. when using @EmbeddedId/@Embeddable and defining the Id
within the target entity class)
yields to NPEs.

public class Entity {

  @EmbeddedId
  private Id id;

  @Embeddable
  public static class Id implements Serializable {
    ....
  }

}

Entity.Id.class.getSimplename == "Id", while the compiled class is named
"Entity$Id.class"

Patch appended.

Best regards,
Eduard
