It seems I don't have enough privileges to update the registry to point to a
newer version of java that is on our network (at least not yet...I am
looking into that battle too).  I poked a bit through the __java__.c to try
to see if there were any other tricks (for example, trying to start a 1.6
version of JVM before running octave), but I have been unsuccessful.

Would you consider allowing environment variables (such as JAVA_HOME) to
override the registry settings for locating the JVM?

Thanks again
