Message Title

If've noticed, the QueryPlanCache was not used, if executing Spring-data -jpa findAll method with an EntityGraph annotation.

I've added the EntityGraph annotations for performance reason's, but it turned out a performance loss: expensive HQL-Query parsing takes place every time the method is excuted.

QueryImpl.java

private List<X> list() {
		if (getEntityGraphQueryHint() != null) {
			SessionImplementor sessionImpl = (SessionImplementor) getEntityManager().getSession();
			HQLQueryPlan entityGraphQueryPlan = new HQLQueryPlan( getHibernateQuery().getQueryString(), false,
					sessionImpl.getEnabledFilters(), sessionImpl.getFactory(), getEntityGraphQueryHint() );
			// Safe to assume QueryImpl at this point.
			unwrap( org.hibernate.internal.QueryImpl.class ).setQueryPlan( entityGraphQueryPlan );
		}
		return query.list();
	}
