Subject [classlib][math]compatibility: different values for BigDecimal(null, mc).toBigInteger() for Harmony and RI
Date Sun, 09 Jul 2006 20:28:46 GMT
The reference implementation doesn't make sense in this example, and it
is highly unlikely that any application will be dependent upon this
behavior, so I propose that we do not apply this patch.

If anyone objects to this decision I will happily reopen it.

Regards,
Tim
