Conversion from OfficeMath to MathML is slower after upgrade

After upgrading Aspose.Word Java from 22.2 to 22.10, the conversion from OfficeMath to MathML is significantly slower. My license does not expire until 2023-02-18.

Here is a sample program that reproduce the problem on my local machine. The time goes up from 5 seconds to about 38 seconds.

HtmlSaveOptions options = new HtmlSaveOptions();

Document doc = new Document("C:\\MathQnA2.docx");
doc.accept(new DocumentVisitor() {
    public int visitOfficeMathStart(OfficeMath officeMath) {
        try {
        catch (Exception e) {
            throw new RuntimeException(e);

        return VisitorAction.SKIP_THIS_NODE;

It looks like the performance decrees occurs starting from 22.7 version of Aspose.Words.

Thanks for the update.
