14730	Display a notice to the user if functionality (imagery layer display) is reduced in case of low memory allocation	aseerel4c26	team	"Currently (see ticket #14593) JOSM silently just stops displaying more than the ""memory-fitting"" amount of background layers in case too few memory was allocated to JOSM (or rather the Java VM).

Would be nice if JOSM would tell the user (with a hint how to [[Help/CommandLineOptions#Javaoptions|fix]]) that there is too few memory to perform an expected action. I mean, there even is a info bar that aerial imagery should be aligned before using it for tracing... :-)
