There is a "feature" of the jikes taskdef that causes it to put the
runtime libraries that are being used to execute ant onto the classpath of any compiled code.

You can defeat this by setting the bootclasspath.
As a workaround for situations where we want to use jikes but we do not need to set the
bootclasspath, we need an directory that exists but is guaranteed to be empty
(and thus harmless to put onto the bootclasspath).

This is that directory. (Yes, I know it isn't strictly empty, the important thing is that 
is has no byte code inside it).
