Hello Ant users, I upgraded from Ant version 1.7.1 to version 1.8.0 and noticed that the performance of my build dropped dramatically. I tracked down the performance loss to an area of my build script where I operate heavily with the Ant-Contrib "For" and "Variable" tasks on a path-like structure. In effect I loop over the contents of a fileset and append a string for each element to a property, which is updated via the "Variable" task. I noticed that, the bigger the fileset is, the greater is the performance loss (9 seconds with Ant 1.7.1 versus 3 Minutes with Ant 1.8.0 for a big fileset!). As it runs fast with Ant 1.7.1, and I did not change my version of Ant-Contrib, I assume that something has changed inside Ant which causes this.
Has anyone noticed related problems with Ant 1.8.0? Any idea? Regards, Christoph
