IllegalArgumentException Aspose.cells for Java

we are trying Aspose.Cells and Aspose.Slides for java for a possible purchase.
We have a problem with the new version of Aspose.Cells (the 2.2.1) while creating a chart from an excel file, the code is as follows :

ImageOptions imgOpts = new ImageOptions();
fileName = sourceFilename + “-chart-” + i + “.png”;
chart.toImage(fileName, imgOpts);

where sourceFilename is “TestSlide_003.xls” and i is a counter whose value is 0, so the complete fileName will be : TestSlide_003.xls-chart-0.png

When the application executes the chart.toImage call we receive the following exception :

Error: Invalid substring range
java.lang.IllegalArgumentException: Invalid substring range

Attached you will find the original xls file. We are trying to convert to an image the chart “Monthly Volume -€ Millions”. Can you help us with it?

This error does not happen with the previous version of Aspose.Cells, the 2.2.0 . With it we have another problem : the image x-axis values are not the same as those of the excel original chart. Is this a known problem? Has it been resolved in the 2.2.1 release?

Thanks in advance for your help,
Ruggero Rizzo.
