+        } else if (source instanceof java.math.BigInteger) {
+            return setObject(targetType, ((java.math.BigInteger) 
source).longValue() );

+                } else if (x instanceof java.math.BigInteger) {
+                    setLong(parameterIndex, ((java.math.BigInteger) 
x).longValue() );

What if the BigInteger contains a number greater than Long.MAX_VALUE or less 
than Long.MIN_VALUE? Should we convert it to a BigDecimal instead of a Long in 
that case?
