Hellow, Aspose Team.
I am using Aspose 20.10 jdk17 version in my project. I am trying to get HTML string from OfficeMath object:
public int visitOfficeMathStart(com.aspose.words.OfficeMath asposeOfficeMath) {
String mathML = asposeOfficeMath.toString(new HtmlSaveOptions());
…
}
This operation causes an exception:
java.lang.RuntimeException: java.lang.NullPointerException
