[Soot-list] Is this a bug?

[Eric Bodden]

Hi Justin.

I have never really used a BriefUnitGraph (and I generally think that
it's of limited use) but what Marco says makes a lot of sense: all
units should go *somewhere* and it's unclear where they should go in a
BriefUnitGraph. I am unsure what the motivation for the current
implementation is, but I guess it's pretty convenient, actually, to
have exception handlers as secondary heads because that means that you
can easily identify and ignore them if necessary.
