Buggy source:
private void verifyAllContainersSignature(){
  Map<String,Boolean> alreadyCheckedContainerMap=new HashMap<String,Boolean>();
  Iterator<String> packageNamesIterator=packageNameToContainerPathMap.keySet().iterator();
  while (packageNamesIterator.hasNext()) {

    String containerPath=packageNameToContainerPathMap.get(currentPackageName);
    if (alreadyCheckedContainerMap.containsKey(containerPath)) {

      X509Certificate verifiedCertificate=null;
      if (!rootPackageNameWithCertificate.isEmpty()) {

        alreadyCheckedContainerMap.put(containerPath,Boolean.valueOf(false));
        File containerToRemove=new File(containerPath);
        if (!containerToRemove.delete())         Log.w(TAG_SECURE_DEX_CLASS_LOADER,"String_Node_Str" + containerPath);
        packageNamesIterator.remove();
      }
    }

}

Fixed version (ground truth):
private void verifyAllContainersSignature(){
  Map<String,Boolean> alreadyCheckedContainerMap=new HashMap<String,Boolean>();
  Iterator<String> packageNamesIterator=packageNameToContainerPathMap.keySet().iterator();
  while (packageNamesIterator.hasNext()) {
    String currentPackageName=packageNamesIterator.next();
    String containerPath=packageNameToContainerPathMap.get(currentPackageName);
    if (alreadyCheckedContainerMap.containsKey(containerPath)) {
      if (!alreadyCheckedContainerMap.get(containerPath))       packageNamesIterator.remove();
    }
 else {
      String rootPackageNameWithCertificate=mPackageNameTrie.getPackageNameWithAssociatedCertificate(currentPackageName);
      X509Certificate verifiedCertificate=null;
      if (!rootPackageNameWithCertificate.isEmpty()) {
        verifiedCertificate=importCertificateFromPackageName(rootPackageNameWithCertificate);
      }
      boolean signatureCheckIsSuccessful=true;
      if (verifiedCertificate != null) {
        signatureCheckIsSuccessful=verifyContainerSignatureAgainstCertificate(containerPath,verifiedCertificate);
        if (signatureCheckIsSuccessful) {
          alreadyCheckedContainerMap.put(containerPath,Boolean.valueOf(true));
        }
      }
      if ((verifiedCertificate == null) || ((verifiedCertificate != null) && (signatureCheckIsSuccessful == false))) {
        alreadyCheckedContainerMap.put(containerPath,Boolean.valueOf(false));
        File containerToRemove=new File(containerPath);
        if (!containerToRemove.delete())         Log.w(TAG_SECURE_DEX_CLASS_LOADER,"String_Node_Str" + containerPath);
        packageNamesIterator.remove();
      }
    }
  }
