Exception"Class Cast" on generating thumbnails using Aspose.Slides for Java

Use slides-18.12-jdk.jar, get thumbnail with chart witch in MasterSlide or LayoutSlide will throw ClassCastException. Chart in Slide is fine. Code is blow

for (int i = 0; i < presentation.getMasters().size(); i++) {
IBaseSlide baseSlide = presentation.getMasters().get_Item(i);
for (int j = 0; j < baseSlide.getShapes().size(); j++) {
IShape shape = baseSlide.getShapes().get_Item(j);
if (shape instanceof IChart) {
BufferedImage image = shape.getThumbnail();
