Aspose.PDF Product Family

Hi there,

We recently upgraded our aspose-pdf for java from version 24:9 to 24:10
Version 24:10 appears to have broken generating a pdf from html when running in headless mode.

Here is a cut down example to reproduce the example and prove that it version 24:10 that is the issue

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import com.aspose.pdf.*;

public class App {
    public static void main(String[] args) {
        System.setProperty("java.awt.headless", "true");
        var html = " <!DOCTYPE html>" +
                "<html>" +
                "<body>" +
                "<h1>A Heading</h1>" +
                "<p>A paragraph.</p>" +
                "</body>" +
                "</html> ";
        var options = new HtmlLoadOptions();
        var pageInfo = new PageInfo();
        pageInfo.setLandscape(false);
        options.setPageInfo(pageInfo);

        var document = new Document(new ByteArrayInputStream(html.getBytes()), options);
        var outStream = new ByteArrayOutputStream();

        document.save(outStream, SaveFormat.Pdf);
        outStream.toByteArray();
    }
}

contents of gradle.build

plugins {
    id 'application'
}

repositories {
    mavenCentral()
    maven { url 'https://repository.aspose.com/repo/' }
}

dependencies {
    implementation 'com.aspose:aspose-pdf:24.10:jdk16'
}

// Apply a specific Java toolchain to ease working on different environments.
java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(21)
    }
}

application {
    // Define the main class for the application.
    mainClass = 'App'
}

if you run

gradle build

then

gradle run

You’ll see the following stack trace

If you change the library back to com.aspose:aspose-pdf:24.9:jdk16 in gradle.build the code will run without blowing up.
