get class from a proxy object

I have the following code. When I call remove, I pass in a proxy that I get from entityManager.getReference. But entity.getClass() fails. How do i get the class information of a proxy

 public <T extends BaseEntity> void remove(T entity) throws RemoveException {
    //get the actual object
    entity = (T)getEntityManager().find(entity.getClass(), entity.getId());
    //delete the object
    getEntityManager().remove(entity);

}

Unknown entity: com.merc.domain.EventLog_$$_javassist_3; nested exception is java.lang.IllegalArgumentException: Unknown entity: com.merc.domain.EventLog_$$_javassist_3
org.springframework.dao.InvalidDataAccessApiUsageException: Unknown entity: com.merc.domain.EventLog_$$_javassist_3; nested exception is java.lang.IllegalArgumentException: Unknown entity: com.merc.domain.EventLog_$$_javassist_3

I might be wrong ... but actually you put your entity into the function, just to get its class and id to find it again and then delete it? I would guess just drop the line:

entity = (T)getEntityManager().find(entity.getClass(), entity.getId());

and it should work.
