ukbobby -- as I've said in every single post about the installers, the international installer will use Java 1.3 unless you delete the 'jre' subdirectory from LimeWire. If you want to use a newer version of Java and not delete the 'jre' directory, use the English installer. Mentions of stability, etc... are a moot point, because they're the exact same program.

LOTR -- The LimeWire installer installs Java 1.3 right now if it doesn't detect any version of Java on the machine. This is because the 1.3 JRE is about 1/3 the size of the 1.4 or 1.5 JRE, and when someone installs LimeWire, we want them to be able to use it ASAP. As I mentioned in an elsewhere (a while ago), we're exploring ways to unify the installers and use a newer version of Java by default.
