[Soot-list] Parsing Soot class files fails with NullPointerException

[Heejong Lee]

Hi.
I've tried to parse Soot class files and failed with NullPointerException.

The command was:
$ java -jar soot-2.4.0.jar -cp soot-2.4.0.jar -allow-phantom-refs -w -v
soot.Main

And the exception was:
...(omitted)
[getGlobalValueNumber] Eliminating unreachable code...
[getGlobalValueNumber]     Constructing
soot.toolkits.graph.ExceptionalUnitGraph...
[getGlobalValueNumber]     Removed 0 statements...

I've figured out targets.next() returned NULL at line 455 of
OnFlyCallGraphBuilder.java:
454         while(targets.hasNext()) {
455            SootMethod target = (SootMethod) targets.next();
456            cm.addVirtualEdge(

Did I type the wrong configuration options? Anybody help?
