2439	JOSM crashed after long time work with WMS.	fatbozz	team	"JOSM display some warning box, which i cant read, because is transparent. I cant close it too. Enter is call more exceptions ( 2nd ex ). Message box is stealing focus. Only way is minimize and maximize programs from ?? task bar ?? (line beside start :) )
I suspect WMS plugin, because lot of time x many WMS tiles can cause crash. I have set -Xmx to 1350M and JAVA is now consuming 1G in Swap.
