Subject Performance dropped with Ant version 1.8.0
Date Mon, 22 Mar 2010 11:32:25 GMT
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?
