[josm-dev] HTTPS changes on osm.org

[Paul Woelfel]

Hi Marc,

you could try to install a more recent version as a second jre and start
JOSM with that java executable.

Java 6 is now really outdated and won't be bug fixed and patched any more.
I know that there can be some applications, which do not support Java 7.
You could also try to run your legacy Java Apps with the old jre and
everything else with a more current jre. This would also be way more secure.
