[Soot-list] couldn't find class printouts

[Andrey_Poliektov at amat.com]

Hi, 

It would be nice to show who's referencing the class which could not be 
found.
In my case there were some references from the code which was never 
executed.

The following change to SootResolver.java seems to be working.

private HashMap classFromReferences = new HashMap(); // refName => HashMap 
of refereeNames

    private void bringToHierarchy(SootClass sc) {
        if(sc.resolvingLevel() >= SootClass.HIERARCHY ) return;
        if(Options.v().debug_resolver())
            G.v().out.println("bringing to HIERARCHY: "+sc);
        sc.setResolvingLevel(SootClass.HIERARCHY);

        String className = sc.getName();
        ClassSource is = SourceLocator.v().getClassSource(className);
        if( is == null ) {
            if(!Scene.v().allowsPhantomRefs())
            {
              String s = "";
              HashMap hm = (HashMap)classFromReferences.get(className);
              if ( hm != null )
                for( Iterator i = hm.keySet().iterator(); i.hasNext(); )
                  s += " referenced by " + i.next() + "; ";

              // There must be an exception here, but I left it as a 
printout to see all the unresolved references at once
              System.out.println( "FATAL ERROR: couldn't find class: " +
                  className + s + " (is your soot-class-path set 
properly?) ");
            } else {
                G.v().out.println(
                        "Warning: " + className + " is a phantom class!");
                sc.setPhantomClass();
                classToReferences.put( sc, new ArrayList() );
            }
        } else {
            Collection references = is.resolve(sc);
            classToReferences.put( sc, new ArrayList(new 
HashSet(references)) );

            for( Iterator i = references.iterator(); i.hasNext(); )
            {
              Object o = i.next();

              String name = null;

              if ( o instanceof String )
                name = (String)o;
              else
              if ( o instanceof ArrayType )
                o = ((ArrayType)o).baseType;
              if ( o instanceof RefType )
                name = o.toString();

              if ( name != null )
              { HashMap entry = (HashMap)classFromReferences.get( name );
                if ( entry == null )
                { entry = new HashMap();
                  classFromReferences.put( name, entry );
                }
                entry.put( sc.getName(), Boolean.TRUE );
              }
            }
        }
        reResolveHierarchy(sc);
    }


Thank you,
Andrey
