Soot resolved an incorrect method signautre

[sarser2048]

Describe the bug
I used Soot to analyze some real-world projects, and found it provides an incorrect method signature, which has redundant single quotes.

Input file
Maven Repo Link

The correct signature should be:
com.fasterxml.jackson.core.util.JacksonFeatureSet: com.fasterxml.jackson.core.util.JacksonFeatureSet with(com.fasterxml.jackson.core.util.JacksonFeature)

However, I got the incorrect results with redudant single quotes in the method name.

To reproduce
Directly use Soot analyze this class file and retrieve the method signature:

for (SootClass klass : Scene.v().getApplicationClasses()) {
  if (klass.isConcrete() && klass.getName().startsWith(PKG_NAME)) {
      for (SootMethod method : klass.getMethods()) {
          if(method.isJavaLibraryMethod()) {
              continue;
          }
          method.retrieveActiveBody();
          if (!method.hasActiveBody()) {
              System.out.println("No Active Body: " + method.getName());
              continue;
          }
          // .......

There is a similar problem when analyzing the following method:

<com.fasterxml.jackson.core.io.ContentReference: com.fasterxml.jackson.core.io.ContentReference 'unknown'()>

This happens when the method name is a reserved name in Jimple:

soot/src/main/java/soot/Scene.java

Line 1535 in 8698b75

private void setReservedNames() {

Otherwise we would have a problem when you write out Jimple files and try to read them back in. See the quotedNameOf method.

look here, same problem: #1697

@MarcMil Thanks for your kind reply. Yes, I know Soot has the reserved names. However, the method quotedNameOf cannot work well when I used it.

For the following two used method signatures:

1st signature
<com.fasterxml.jackson.databind.introspect.CollectorBase: com.fasterxml.jackson.databind.introspect.AnnotationCollector collectDefaultAnnotations(com.fasterxml.jackson.databind.introspect.AnnotationCollector,java.lang.annotation.Annotation[])

2nd signature
<com.fasterxml.jackson.core.util.JacksonFeatureSet: com.fasterxml.jackson.core.util.JacksonFeatureSet with(com.fasterxml.jackson.core.util.JacksonFeature)>

The first signature can be converted to (annotation -> 'annotation'), but we cannot get the quoted version (with -> 'with') of the second signuatre when invoke Scene.v().quotedNameOf().

Soot may only use dot to seperate the given name, however, we often use method signature to get a resovled SootMethod. I think the method quotedNameOf should be improved.

And, another problem is, not all reserved names will be changed to quoted version, e.g., void.
