JRGraphics2DExporter.exportReportToGraphics2D() does not export all the pages

JRGraphics2DExporter.exportReportToGraphics2D() does not export all the pages JRPrintPage from the JasperPrint. It only exports the "startIndex" page even when JRExporterParameter.PAGE_INDEX is not set.

Code Snippet from exportReportToGraphics2D():

//

List pages = jasperPrint.getPages();

...

...

try

{

JRPrintPage page = pages.get(startPageIndex);

exportPage(page);

}

//

Expected behavior: Loop through and export all pages from startPageIndex to endPageIndex.
