JPA COUNT returns a Long
When extracting the count from the table JPA returns long based on the type of query used.

JPQL

Query query = em.createQuery("SELECT COUNT(p) FROM PersonEntity p " );
query.getSingleResult().getClass().getCanonicalName() --> java.lang.Long

Native Query

Query query = em.createNativeQuery("SELECT COUNT(*) FROM PERSON");
query.getSingleResult().getClass().getCanonicalName() --> java.math.BigInteger

If it is Native Query big Integer is returned or if it is JPQL then Long is returned.

So before assigning to Integer the value should be typecasted.

 int count = ((Number)arrCount.get[0]).intValue();
 System.out.println(count);

Needs to be Removed
