Sounds useful.

Do you mean : your change is bringing an optimization for taskdefs which 
are done based on jars which have already been loaded by the launcher, 
presumably because they are in $ANT_HOME/lib or in a -lib directory  ?
And not if the taskdef is requiring extra jars or directories which were 
not included when ant got started ?
