Scala's jar files are compiled with JVM 1.5, as can be seen by looking into the META-INF/MANIFEST.MF file. Here is 2.8.1: Created-By: 1.5.0_22-b03 (Sun Microsystems Inc.).
The Scala compiler generates output that is compatible with jvm-5 (see scalac -target). Also, it has some magic to enable use with jdk 1.6, in which String has added a method that Scala defines on WrappedString.

RichString is now StringOps/WrappedString/StringLike in 2.8.1 or? (Someone corrected me on that last week)

@oluies It is. What can I say? I'm an old hand in Scala. ;-)
Scala is compiled with the scalac compiler and not javac. To run the Scala code you need Java runtime/sdk version 1.5 or later and the scala library jar.
Version 2.7.7 and 2.8.1 are the common versions used today. If you start a new project now you should aim for 2.8.1 or 2.9 (which is going to be available soon-ish). Download site is here
