I think I got that....I was taking JRE and Interpreters as two different things. I thought it was only the Java Interpreter that vendors always provided alongwith their software and JRE was some run time environment provided by SUN.
But it is the JRE which can be bundled or optionally not bundled by the software vendor. And JRE encompasses Java Runtime Interpreter. End-users can download and install the Windows JRE themselves if not provided by the vendor from Sun's Java software website. Once a user has installed the JRE, it can be used to run any number of Java applications. The JavaTM Runtime Environment (JRE) is the minimum standard Java platform for running applications written in the Java programming language. It contains the Java virtual machine*, Java core classes, and supporting files.
I also got related info from here:
