XliffReader.close() do not close the documents in a Exception case

[Davide Giunta]

The XliffReader do not closes the resource in case of an Exception.

This results in a FileSystemException if you try to delete the file after that (I know it’s very rare case)

java.nio.file.FileSystemException: Some xliff file: The process cannot access the file because it is being used by another process.

Example Code:

        try(XLIFFReader reader = new XLIFFReader(XLIFFReader.VALIDATION_MAXIMAL))  {
            reader.open(Paths.get("Some File Path").toFile());

            if (true) {
                throw new RuntimeException("Some strange Exception");
            }
        } catch (Exception e) {
            System.out.println("Exception gefunden - " + e);
        }

        try {
            Files.delete(Paths.get("Some File Path"));
            System.out.println("Success");
        } catch (IOException e) {
            System.out.println("Something went wrong!");
        }
