v2.1.0, $count is not working whatsoever; pagination is not working #330

Open akaFood opened 2 weeks ago

akaFood commented 2 weeks ago

when using $count = true or enable paginaiton, the following error is returned: "class java.lang.Integer cannot be cast to class java.lang.Long (java.lang.Integer and java.lang.Long are in module java.base of loader 'bootstrap')". The error was thrown at JPAExamplePagingProvider.class, getFirstPageMethod, Long maxResults = countQuery.countResults();. Inside JPAJoinCountQuery.class, line 47 - return (Long) result.get(0); I saw that the total records count returned was Integer type, and its getting casted to Long, hence why the error occurred.
