I don't like the look of that! You shouldn't be working as root when you are
doing programming.

Why do you use javac? There's a much better compiler called guavac (a GNU
Java, I believe) which runs a zillion times faster than Sun's javac -
probably as fast as gcc. Not just Linux, I've tried java on Windows, Digital
Unix and even Solaris -- none of them come even close to be being as fast as
guava. Although I have 32 megs of RAM, my guess is that
guavac should be able to manage with 16 megs too. the interpreter (i.e.
java) is called kaffe. I couldn't run the interpreter on RH5.2, it just
crashed. However, it works great on RH6.0.
