A DESCRIPTION OF THE PROBLEM :
java.math.BigX contains methods of the form "BigInteger
add(BigInteger)". They should be of the form "Number
add(Number)" allowing BigDecimals and BigIntegers to play
nicely together. This will require a redesign.

This bug can be reproduced occasionally.

CUSTOMER WORKAROUND :
if (lvalue instanceof BigInteger) {
    if (rvalue instanceof BigInteger) {
        lvalue =
((BigInteger)lvalue).add((BigInteger)rvalue);
    } else {
        lvalue = (new
BigDecimal(lvalue)).add((BigDecimal)rvalue);
    }
} else {
    if (rvalue instanceof BigInteger) {
        lvalue = ((BigDecimal)lvalue)
            .add(new BigDecimal((BigInteger)rvalue));
    } else {
        lvalue =
((BigDecimal)lvalue).add((BigDecimal)rvalue);
    }
}
