They must be customized - the JVM is the abstraction layer between the OS
and the java program. But for the Java program itself, all JVM are the
same.

No. I'm a fulltime Java programmer, and we are deploying our software to
Windows, Sun and HP - and there are no changes to the code for these
platforms (except where you rely on OS features like calling external
programs).
If have also used both the Sun and IBM JDKs on Linux for my own software,
and no changes were required to run the programs. I have even reports of my
software running with the kaffee VM and GNU classpath.

So, Java is really WORA if done right.
