This is probably related to the bug we found a few days ago. Currently, the ConstValue attribute of a static field was lost when a class is converted to the soot internal representation. We had some discussion before, but didnot decide a solution yet.For example, gnu/java/lang/CharData.class(or java) in the glibj.zip has a couple of static string constant definitions, but newly converted CharData.class has just static string reference fields.
