I do not know hibernate, so Ihaven't the sligstest idea of why
get("EB") returns BigInteger or why you do not cast it to BigInteger
instead of BigDecimal.

But if your problem is it sometimes has Bigdecimal and sometimes
BigInteger you could try casting it to the parent, Number, which is
the one specifying longValue() and would make the code work with both.
