I have some environments stuck with Java 1.3 so i planned to use Ant 1.7.1. I gave Ant 1.8.2 a try (I should have tried that from the start obviously, sorry) and the performance gain was tremendous as the task when from 42 minutes to 9 minutes. > Another thing to look at is the way you describe your include/exclude > patterns, if there are any, that is.

I'll look into separating the tasks into targets called by the wrapper.
