Why exactly do you want to know? There's probably a
work-around, but the solution would depend on what in
particular you're trying to accomplish.
Although it won't help you a bit with your problem,
it might make you feel better to check out the official
java bug list. Some people feel strongly that env variable
access should be possible, or barring that, that the
documentation should be clarified.

Tomcat cheats. The startup scripts do something along
the lines of:
$JAVACMD $TOMCAT_OPTS -Dtomcat.home=${TOMCAT_HOME} org.apache.tomcat.startup.Tomcat
"$@" &
Of course, that's platform specific. You can check this
out on your own by looking in the "bin" directory of a
tomcat installation, where you will find a maze of twisty
little shell/bat scripts, all alike.
