[Soot-list] Problematic behavior of Scene.v().addBasicClass (nightly build vs. soot 2.5)

[Marc-André Laverdière]

Hello Khan,

Thanks for your patience. Everybody has been busy lately :(

What you are telling is that {path} contains the manager.MyManager
class, that it gets loaded in 2.5, but not in the latest development
version?

My first question is: where did you get the nightly build?  The right
place is here: http://vandyk.st.informatik.tu-darmstadt.de/abc/

Assuming you got the right nighly build, that really looks like a
regression.

First, I would ask you to put the bug report in github, so that we have
some traceability: https://github.com/Sable/soot/issues/new

Second, we need to find out if the class is somehow malformed or
something like that. Is this a class you compiled yourself? With a
recent Java compiler?

Third, if the problem is not with the class file, Would you please send
a minimal working example by email? Ideally, it should fit in one or two
.java files.
