> The action clean-working-directory runs out of heap space while cleaning up huge working
directories (30GB / 500.000 files & directories in our case):

> Caused by: java.lang.OutOfMemoryError: Java heap space
>  The issue seems to be caused by the implementation in CleanWorkingDirectoryAction: the
FileSetManager used to delete the working directory first scans all files & directores
to create an object representation of the tree and then deletes the tree by scanning through
the objects. As no filter condition is required using org.codehaus.plexus.util.FileUtils to
directly delete the tree would avoid these kind of problems.
> I'll attach a patch based on 1.2.3.
