[jira] Updated: (HARMONY-6271) [classlib][math] BigDecimal.divide should throw an ArithmeticException instead of OutOfMemory for too large scales

Catherine Hope updated HARMONY-6271:
------------------------------------

    Attachment: bigdecimal-patch.txt

Fix simply to change the OutOfMemoryError to an ArithmeticException (the error message remains the same as this shouldn't be matched).
Test added to BigIntegerDivideTest.java (testCase25)

> BigDecimal.divide should throw an ArithmeticException instead of OutOfMemory when called with a scale that can't be satisfied with the available memory.  The exception defined in the specification is:
> "throws ArithmeticException - if divisor is zero, roundingMode==RoundingMode.UNNECESSARY and the specified scale is insufficient to represent the result of the division exactly."
> Which doesn't say what to do in this precise occurrence (though it doesn't say it may throw an OutOfMemoryError), but both Sun and IBM Java implementations have this behaviour.
