Require assistance in Postgres + Hibernate : Error:java.math.BigInteger cannot be cast to java.math.BigDecimal

Require assistance on the below:

Code snippet:
Map<String,Object> ic;

//Populate values for ic

long count = ((BigDecimal)ic.get(“EB”)).longValue();


Getting the below error:
    java.math.BigInteger cannot be cast to java.math.BigDecimal
    ®java.lang.ClassCastException: java.math.BigInteger cannot be cast to java.math.BigDecimal

Since this is not part of a query doing select cast (EB as bigint) will not help in this case:

Can u let me know the solution for this?
