Java is platform independent because the JVMs are platform specific.

Java bytecode is exactly the same, but what you need to run on Windows is different from Linux and that is different from Mac.
So the different JVMs take the same bytecode and run it for their machines.

Where do you see the contradiction between Java being platform-independent and the JVM being platform-dependent?
 
It is sorta covered in the JavaRanch Style Guide.
