The original poster was looking for a per-user solution to JVM
switching. I'm guessing from the name (system-switch-java) that it
switches the whole system's choice of java (javac, plugin, etc.) as
opposed to just the user's. And that it probably requires some kind of
elevated access permissions. Is it a frontend to the alternatives
