ChoiceFormat inconsistency between applyPattern() and setChoices()

ChoiceFormat::applyPattern does not allow intervals to be set in non-ascending order.

ChoiceFormat::setChoices does allow intervals to be set in non-ascending order.

These setter methods should be able to create consistent ChoiceFormat objects.

For example,

new ChoiceFormat(new double[]{1,1}, new String[]{"foo","bar"}) // no exception
new ChoiceFormat("1#foo|1#bar") // throws exception

It would be great if these could be consistent, but changes at this point would cause compatibility issues. This difference should at least be emphasized in the specification.
