[Soot-list] Problems with jimple parser

[Eric Bodden]

Hi Bernhard.

I wonder: What does javac do with package-info.java files? Does it
compile them to .class files at all? If not, then maybe Soot should
not even output those files in the first place. After all, those files
do not actually contain class definitions.
