Aspose License not working correctly for spring-boot application

Question

I have a spring-boot application which has a public rest api endpoint. The api extracts text from a given pdf file. I am loading the Aspose license in a static initialising block and it loads correctly.

public class AsposeLicenseLoader {

  private static Logger logger = LoggerFactory.getLogger(AsposeLicenseLoader.class);

  private static boolean isLicenseLoaded;


  public static void doLoad(AsposeConfig asposeConfig) {

    String location = asposeConfig.license().location();
    logger.debug("Loading Aspose license \"{}\"", location);
    try (InputStream is = AsposeLicenseLoader.class.getClassLoader()
        .getResourceAsStream(location)) {
      com.aspose.pdf.License pdfLicense = new com.aspose.pdf.License();
      pdfLicense.setLicense(is);
      isLicenseLoaded = true;
      logger.info("Aspose  license loading completed");
    } catch (Exception e) {
      logger.error("Unable to load the Aspose  license", e);
    }
  }


  public static boolean isAsposeLicenseLoaded() {
    return isLicenseLoaded;
  }

When I try to extract text from pdf the output shows the license is not applied correctly with the following output.

Evaluation Only. Created with Aspose.Pdf. Copyright 2002-2017 Aspose Pty Ltd.

The the text extraction logic in my application below.

com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document(filePath);

    // Create TextAbsorber object to extract text
    com.aspose.pdf.TextAbsorber textAbsorber = new com.aspose.pdf.TextAbsorber();

    // Accept the absorber for all the pages
    pdfDocument.getPages().accept(textAbsorber);

    // Get the extracted text
    extractedText = textAbsorber.getText();

However if I explicitly load the license just before the text is extracted then it applies the license correctly and extracts the full text from the file. As per the documentation of aspose I only need to load the license once and not for each incoming request. Does anyone know if I am missing anything here?

I have looked at the official aspose documentation and followed their instructions. Also looked at similar issues posted by other members. https://forum.aspose.com/t/loading-aspose-license-in-aspose-java/62945/2
