Description

So, SVN has an option to use '_' instead of '.' for its private directories.
I discovered the long and hard way that encountering these directories causes Tapestry to freak out:

It will use up all available memory and then crash.
Unfortunately, _svn is actually a valid java package name so I think an actual specific exception will have to be made to ignore these directories.
As I understand it, some developers have this SVN option set because Microsoft IIS has the opposite problem: It will fail when there are directories named .svn but not with _svn
