We are looking into this inquiry. For Aspose.Cells, we have logged an investigation ticket into our system with ID CELLSJAVA-42606. We will update you here once there is some information or a fix version available in this regard.
Regarding Aspose.Words for Java, it is possible to use this API without java.awt.Paint when the documents do not contain images with gradient fill.
But we think that your Java ME Embedded Configuration not only misses the java.awt.Paint class but also some other java.awt.* classes are missing. Please tell what core Java classes are absent in your Java ME Configuration?
It depends on ClassLoader and its configuration. Some ClassLoaders have lazy configuration - they load a class only by demand. Other ClassLoader (like yours) load all referenced classes at startup. But this is not important if you want to save to PDF.
I am afraid, this is not possible as PDF conversion engine of Aspose.Words for Java itself demands deep using of graphics. Asposee.Words for Java internally uses almost the same classes when performing conversion to PDF or conversion to Image formats (.tiff, .jpeg, .png etc). So in this case it heavily depends on system graphics packages.
In a nutshell, using Aspose.Words for Java API without java.awt.Paint is possible, only if input documents do not contain images (with gradient fill) and output formats do not involve image formats (.gif, .tiff, .pdf, etc.). You should be able to convert Word formats to other Word formats (.docx, .doc, .rtf etc) but for this your ClassLoader should have lazy configuration i.e. to load classes only by demand.
For PDF conversions, I am afraid, you have to either use “Aspose.Words for Android via Java” or “Aspose.Words for Cloud”.
