These aren't in 1.x, but new stuff in 2.x, which means that this behaviour
is a regression.

This is a regression. for 1.0 you can change dir by setting the relevant
data directory "test.build.dir".
I don't see any reason why the static stuff is really needed, it's used in
various tests, but that could be changed -especially as the static methods
aren't in 1.x.
Why not file a JIRA -and perhaps a patch?
