False information, JOSM actually works (and even better) in 64-bit mode !

 To avoid the Java console windows staying open, you can use `javaw.exe` instead of `java.exe`.

+Be carefully if you run a 64 bit version of Windows, the Java Runtime (update every month) may be installed in 64-bit when visiting the Java web site with a 64-bit version of your browser, or in 32-bit otherwise.
+Both Java platforms will coexist on the PC, but by default the file associations will run first the 32-bit version, creating VMs limited to a maximum of 247MB (if your VM size reaches this limit, due to the volume of data loaded, JOSM may become very slow or unresponsive).

+But you may also uninstall the 32 bit versions of Java (which remains only for old 32-bit browsers using applets, and don't need applets in those browsers, or for 32 bit OSes where this is the only choice available).

+If only a 64 bit version of Java is installed on a 64 bit version of Windows (and with a Java version higher or equal to the minimum version specified in the JNLP if you use JavaWebStart to download/update and launch JOSM), JOSM will start automatically in a 64 bit Java VM (with more memory available to handle larger volumes of data, and better performance). Otherwise it will launch in a 32 bit Java VM, unless you add VM parameters to the command line to locate and use the 64 bit version of Java.
