Hi SS, If JTS used JUMP then it would need to be under GPL.
GPL software such as JUMP can use non-GPL components such as JTS. The rule (I think is) if you have an application that uses GPL components, those components which utilize GPL components must also be GPL. I think a general good guiding principal is if you want to define an interface that components can implement and you want to allow proprietary implementations you should define that interface using a less restrictive license than GPL. Personally I'm not a fan of GPL due to the confusion it causes. As an open source software developer I want people to use my code not have to worry about dealing with lawyers.
