If you run ANT in verbose mode (-v) what does it
output as the string that is generated...?
On a side note, properties are immutable in ANT and so
you can shorten (actually eliminate) the <condition>
check on the registry.cache.dir and just make it:
<property name="registry.cache.dir" value=""/>
because if registry.cache.dir is already set to any
value the <property> setting will be ignored, however
if registry.cache.dir has not been set it will be set
to a blank string
