Description
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 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... :-)

Yes, the layer is hidden to avoid a out-of-memory situation that would lead to a JOSM crash (corrupt data, ...). Displaying a warning about this the user worked some time ago. I'll have a look into it.
Currently, we just use a hard limit for all imagery layers (like size of total heap - size of expected JOSM memory usage). Accounting is just a very rough estimate, so we may be off by a lot. This is not optimal.
Thank you!
