Hi, Attached is very simple patch which reduce josm memory usage.
I've made some memory benchmarks using attached patch and also earlier timestamp and tagged patch. Here are the results: no patch 251MB string inter patch 224MB, 27MB saved tagged patch 223MB, 1MB saved timestamp patch 185MB, 38MB saved Especially the timestamp patch saves much more memory than I have expected. The tests were made using 80MB osm file. I've used jconsole to perform GC and measure heap size. -- Jiri Klement
