Hello,

Our workspace has various symlinks going in different directions, so simple directory scanning ends up in infinite recursion. I get the following output at the end of all my test jobs:

Build step 'Execute shell' marked build as failure

In my (limited) ability to poke around ant it seems like a slowScan() needs to be performed, but I can't figure out where to tickle that in the API.

Thanks,
Andrew
