What versions of Java are usually installed in browsers, is it safe to read 1.4?

Is there any website / analysis of what most versions of Java use on the WWW? This data seems to be unavailable in web server logs (compared to Flash versions)

Is it safe to install, for example. Java 1.4.2 as the minimum requirement for our applet, or are there many more users using Java 1.1 (MS one) or Java 1.2-1.3?

This is another difficult process to upgrade Java if it is too old, for example. Administrator rights are required on a Windows computer, and this is also difficult on some Linux distributions.

You might consider starting a Java network. This allows you to use any latest version. It even allows you to use a version that is older than the default version for the browser. for example, if you have a program that works only with Java 5, but Java 6 is installed.
