Description:
Add method count in classes Criteria and Query.
Example:

final int PAGE_SIZE;
int position;
...
Query query = ... // build complex query with many parameters
int pageNum = position / PAGE_SIZE + 1;
int pageCount = query.count() / PAGE_SIZE + 1; // <-- HERE
System.out.println("Page " + pageNum + " from " + pageCount);
query.setFirstResult(position);
query.setMaxResults(PAGE_SIZE);
List page = query.list();
System.out.println(page);

Not necessary will twice create the similar Query or Criteria. 
By Criteria always easy build sql count query.
For Query.count() throw exception if create sql count query impossible.
