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.

#14704 is a prerequisite."	enhancement	assigned	major		Core validator			modularization
