The main issue with jscience is lack of maintenance. It was invented around the time of JSR 275 which was ultimately rejected. The newer "units of measurement" work is in JSR 363 and JSR 385, while the currency/money stuff is in JSR 354.
Even the "units of measurement" work is a bit fragmented. If you want to use KILOMETERS and MILES for instance, or use FEET, you have to mix and match different libraries with the standard, and the different libraries are all based on different vintages of the standard. It would be nice to have a single library to be able to use. But I'd check with the JSR folks first to see if there was an interest in having an ASF implementation. I wrote a blog about using these APIs with Groovy here: https://groovy.apache.org/blog/life-on-mars-units-of Cheers, Paul.
