Brett Porter commented on CONTINUUM-2119:
-----------------------------------------
I think that was captured in CONTINUUM-1156, I may have misinterpreted the need
though. It depends on whether this is still reproducible with the version we
currently use or if we need to go to v3.x
> Cleaning up large working directories fails with OutOfMemoryError

> 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.
