Method o.n.m.maven.apisupport.ModuleJarAccessibilityQueryImpl.getBadgeIcon() loads an icon (a JAR resource) in EDT.

If I remember correctly, former Maven support maintainer Milos didn't like the idea of loading of this type of resources in background, as it significantly increases complexity of the code, and I don't know of any other way to fix this slowness.

Reassigning to projects/Maven. Marking as WONTFIX, but feel free to reevaluate.

Thank you for reporting.
