Buggy source:
@Override public Conditional<Instruction> execute(FeatureExpr ctx,ThreadInfo ti){
  AnnotationInfo[] annotations=getFieldInfo(ctx).getAnnotations();
  for (  AnnotationInfo ai : annotations) {
    if (ANNOTATION_CONDITIONAL.equals(ai.getName())) {
      StackFrame frame=ti.getModifiableTopFrame();
      FeatureExpr feature=Conditional.createFeature(fname);
      featureNumber++;
      System.out.println("String_Node_Str" + featureNumber + "String_Node_Str"+ fname);
      IChoice<Integer> create=ChoiceFactory.create(feature,One.valueOf(1),One.valueOf(0));
      frame.pop(ctx);
      frame.push(ctx,create);
      break;
    }
  }
  if (!ti.isFirstStepInsn()) {
    FieldInfo fieldInfo;
    try {
      fieldInfo=getFieldInfo(ctx);
    }
 catch (    LoadOnJPFRequired lre) {
      return ti.getPC();
    }
    if (fieldInfo == null) {
      return new One<>(ti.createAndThrowException(ctx,"String_Node_Str",(className + '.' + fname)));
    }
    ClassInfo ciField=fi.getClassInfo();
    if (!mi.isClinit(ciField) && ciField.pushRequiredClinits(ctx,ti)) {
      return ti.getPC();
    }
    ElementInfo ei=ciField.getStaticElementInfo();
    ei=ei.getInstanceWithUpdatedSharedness(ti);
    if (isNewPorFieldBoundary(ti)) {

        return new One<Instruction>(this);

    }

Fixed version (ground truth):
@Override public Conditional<Instruction> execute(FeatureExpr ctx,ThreadInfo ti){
  if (getFieldInfo(ctx).getAnnotation(ANNOTATION_CONDITIONAL) != null) {
    StackFrame frame=ti.getModifiableTopFrame();
    FeatureExpr feature=Conditional.createFeature(fname);
    featureNumber++;
    System.out.println("String_Node_Str" + featureNumber + "String_Node_Str"+ fname+ "String_Node_Str"+ className);
    IChoice<Integer> create=ChoiceFactory.create(feature,One.valueOf(1),One.valueOf(0));
    frame.pop(ctx);
    frame.push(ctx,create);
  }
  if (!ti.isFirstStepInsn()) {
    FieldInfo fieldInfo;
    try {
      fieldInfo=getFieldInfo(ctx);
    }
 catch (    LoadOnJPFRequired lre) {
      return ti.getPC();
    }
    if (fieldInfo == null) {
      return new One<>(ti.createAndThrowException(ctx,"String_Node_Str",(className + '.' + fname)));
    }
    ClassInfo ciField=fi.getClassInfo();
    if (!mi.isClinit(ciField) && ciField.pushRequiredClinits(ctx,ti)) {
      return ti.getPC();
    }
    ElementInfo ei=ciField.getStaticElementInfo();
    ei=ei.getInstanceWithUpdatedSharedness(ti);
    if (isNewPorFieldBoundary(ti)) {
      if (createAndSetSharedFieldAccessCG(ei,ti)) {
        return new One<Instruction>(this);
      }
    }
    ei=ei.getModifiableInstance();
    return put(ctx,ti,ti.getTopFrame(),ei,true);
  }
 else {
    ClassInfo ciField=fi.getClassInfo();
