NullPointerException Is Thrown When Loading a Presentation File in Java

Aspose.Slides Product Family
1

Hello,

Since 25.8 (inclusive) version, I am not able to instantiate a lot of presentation files. Reason:
Caused by: java.lang.NullPointerException: Cannot invoke "com.aspose.slides.ms.System.Xml.t2.getLocalName()" because the return value of "com.aspose.slides.ms.System.Xml.n8.d6(int)" is null

Here is the test code for reproduction:

@org.junit.Test
    public void forum() throws Exception {

        java.lang.String presentationsDirAbsolutePath = "${absolute_path_to_extracted_zip}";

        java.nio.file.Files.list(new java.io.File(presentationsDirAbsolutePath).toPath()).forEach(x -> {
            try (java.io.InputStream presentationInputStream = new java.io.FileInputStream(x.toFile())){
                new Presentation(presentationInputStream).dispose();
            } catch (java.io.IOException e) {
                throw new java.lang.RuntimeException(e);
            }
        });
}

Link to presentations directory zip (valid until Apr 8, 2026.).

Please evaluate for fixing.

Kind regards,
Zeljko
