Once more, I think this is a Polyglot bug that manifests itself in both
abc and Soot, since both use Polyglot to parse Java source.

It's easy to change to a new version of soot -- in fact, if you track
abc HEAD, then in the libs/ folder you'll have a nightly-built
sootclasses-custom.jar.

Changing to a new version of Polyglot is not that simple, as essentially
all of the abc frontend depends on Polyglot, and so each upgrade is
connected with extensive testing and fixing. Going to 1.3.5 might be
possible with a few days' work on our part, but we looked at 2.* and
decided it was not worth the effort of porting abc to it (in fact,
that's when we started the alternative frontend).

I'd suggest checking whether Polyglot 1.3.5 has fixed the bugs you are
seeing -- my guess would be that it hasn't.

Hm, both these classes are generated and should be left in abc-ja.jar...
what classpath are you using? What happens if you use abc-ja/classes on
the classpath rather than abc-ja.jar?
