[Soot-list] soot class path issue

[Marc-André Laverdière]

Hello Ashish,

Please reply to list in the future :)

IIRC, that specific class is in a separate jar, not in rt.jar.

That doesn't solve the issue you are having though. I double-checked the
code (last time I pulled was yesterday). Scene.getSootClassPath does
some concatenation magic. Have you tried comparing the values of
getSootClassPath vs the variable?

BTW, this looks like a major break of encapsulation to me. Do you feel
like changing it and making a pull request? :)
