Divest? I object to removing Fraction from [lang], as its a very core
concept tat is missing from the JDK. And thee are many users who would
just want Fraction and none of the rest of the [math] library.
The [lang] maths package is fo non-mathematicians. The [math] library is
for serious mathematicians. Big difference.
As per the commons charter, there is nothing wrong with having
duplicated code/concepts in Commons.
