The message appears before JOSM starts loading plugins.

It doesn't seem to have any effect on the operation of JOSM, and normally goes away when I start it again.

This has been going on for a while, like for the last 300-400 SVN revisions. Filing it because I couldn't find an existing bug."	defect	closed	minor		Core	latest	othersoftware	javabug
