Fixed version (ground truth):

  }

    throw new IllegalArgumentException("String_Node_Str" + expected.getAbsolutePath() + "String_Node_Str");
  }
  for (  File expectedFile : getFiles(expected)) {
    String completeRelativePath=expected.getPath();
    int index=expectedFile.getPath().indexOf(completeRelativePath) + completeRelativePath.length();
    String relativePath=expectedFile.getPath().substring(index);
    File filteredFile=new File(actual,relativePath);
    try {
      Assert.assertEquals("String_Node_Str" + expectedFile.getPath() + "String_Node_Str",expectedFile.exists(),filteredFile.exists());
      if (ArchiveUtils.isArchiveAndIsSupported(expectedFile.getName())) {
        checkArchiveIsAsExpected(filteredFile,expectedFile);
      }

      throw new RuntimeException(e);
