Aspose.HTML Product Family
1

Hello,
I perform conversion from HTML to PDF with following Java code:

      final String myDocument = "./testcases/Functional programming - HaskellWiki.html";  
      final String myDocumentOut = "./testcases/out/Functional programming - HaskellWiki.pdf"; 
      final com.aspose.html.saving.PdfSaveOptions soptPdf = new com.aspose.html.saving.PdfSaveOptions();
      com.aspose.html.converters.Converter.convertHTML(myDocument, soptPdf, myDocumentOut);

most of file works fine, but with attached file
Functional programming - HaskellWiki.zip (12.1 KB)

I got following exception:

I am getting similar exception with Aspose PDF:
com.aspose.pdf.internal.ms.System.lh: element already exists

The stacktrace is different in my case.

com.aspose.pdf.internal.ms.System.lh: element already exists

The following code on new Document(sourceFile, options) throws the exception.

public class HtmlToPDFConversionTest {


    @Test
    public void testHtmlToPDFConversion() {
        String sourceFile = "C:/Users/Lenovo/Downloads/sourceFile.html";
        Path documentPath = Paths.get("testpdf.pdf");
        HtmlLoadOptions options = new HtmlLoadOptions();
        options.setHtmlMediaType(HtmlMediaType.Print);
        try (Document document = new Document(sourceFile, options)) {
            document.save(documentPath.toString());
        }
    }
}

I am not sure if my issue is related with the one OP has asked. Would like to provide more info on code and environment where this is reproduced. Please let me know if this issue has been already identified, if not how to proceed from this point.
