Like shown in the .java file:

  $ javac -d . -target 1.1 javaversion.java

with a Sun JDK (the Java reference implementation), probably 1.4 or 1.5.

Not with the OpenJDKs, because the current JDKs no longer allow '-target 1.1'.

But Haelwenn explained that it can be done with the Eclipse compiler for Java
(which was also used for bootstrapping GCJ as long as GCC supported Java).
