The class BigDecimal can be and sometimes is subclassed. The spec of BigDecimal.hashCode is improved slightly by explicitly stating it is a function of the unscaled value and the scale of the BigDecimal, the same fields examined by equals.
It is a conscious choice to *not* explicitly state what the exact hash function is.
As the behavior of hashCode is mostly implied from equals, I don't think a CSR is necessary in this case.
