Hi Viatcheslav! The quickstart has a modules example, but I have not tired it since the introduction of ImageN.
We have talked about removing JAI18N (and internationalization) from ImageN codebase as it does not add much value vs how much work it is to maintain. Please report it to the ImageN issue tracker and we can discuss further. And yes it is these kind of things we want to sort out before ImageN 1.0 is made. Thank you very much for the feedback! - - Jody Garnett On Dec 8, 2025 at 7:56:50 AM, Viatcheslav Sysoltsev < [email protected]> wrote: > Hi everyone, > > does anybody use geotools in java9-modularized project (former project > jigsaw)?
