Comparing the code for the JDBC driver to tds_money_to_string() in
freetds/src/tds/numeric.c, it looks as if the Java code avoids the
problem you describe, but introduces another.  Both MONEY and SMALLMONEY
types are defined to preserve accuracy to a ten-thousandth of a monetary
unit, but the JDBC driver in Tds.getMoneyValue appears to be discarding
the two least significant decimal digits of this precision.  Is this
intentional?  It seems like an (inappropriate) U.S.-centric view of
monetary values.
