Why would you want to use the new compiler if you have the old one on the machine? I'm not really understanding the use case for the bootclasspath version. Sam

And at least some parties do not use javac's bootclasspath mechanism to
limit the core API that the compiled code uses; a third party API
checking tool is used instead. In such workflows, by design the javac
check is circumvented. (I don't necessary think this is a good workflow,
but it is being used.)
