Beware casual use of JScience.org if your model is to become persistent. You might be walking into a snake pit.
When I first stumbled upon the JSR-275 standard units RI at JScience.org last autumn, I was very impressed with its careful design and eager to use it in my projects. That was before I began working on JPA persistence annotations for my data model. Now I regret using this otherwise wonderful package, for I've become entrenched in an ugly decision between shedding JScience.org dependencies entirely and reimplementing, annotating a partial branch of JScience.org for use in my project, or building some kind of bridging data class and corresponding transformer layer.
Neither option is attractive. Lesson learned.
