Please note that the latest version of Aspose.Words for Java is completely auto-ported from .NET, i.e. we do not write code for Aspose.Words for Java; it is generated out automatically from C# code of Aspose.Words for .NET.
The APIs are same for Aspose.Words for .NET and Java. You can use Document.TrackRevisions to achieve your requirement. Setting this option only instructs Microsoft Word whether the track changes is turned on or off. This property has no effect on changes to the document that you make programmatically via Aspose.Words.
