Java 1.5, Ant 1.6 and rmic

I've just been compiling Bodington on Java 1.5 and I noticed that the rmic task was always running. After a bit of googling I came across a post on an ant developers blog which explained what was going wrong and led me to the bug report. I've committed a fix to WebLearn HEAD and will probably push this fix across to Bodington HEAD next week.
