15182	Standalone JOSM validator	Don-vip	Don-vip	"During Java 9 compatibility effort (#11924) I wondered if modularization could be applied to JOSM, which currently is a big spaghetti-based monolithic jar.

A clean modular architecture would be a huge task (don't know if it would really be possible at all, as we have a lot of interwoven dependencies) but I'd like to see if we can achieve a more affordable intermediate state, where we could build a standalone version of JOSM validator that could be run as follows:

`java -jar josm-validator.jar data.osm -o warnings.xml`

This jar having no dependency on AWT/Swing/JavaFX. This way it could be run for example by a Java 9 server VM which does not include the java.desktop module.

It would not change anything on JOSM editor except probably some API changes, but as little as possible."	enhancement	assigned	major		Core validator			modularization
