http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html#exec(java.lang.String[],%20java.lang.String[])

It seems that there is no (obvious) way to add variables to the
environment from java 1.4. You can either let the child process inherit
the full environment or specify the exact environment.

In Java5, there is a better scheme: ProcessBuilder.

So I'm contemplating the idea of dropping the Java 1.4 restriction and
moving forward.
