I am using net.sf.jasperreports 6.20.0 to generate PDFs. However, when processing a bulk amount of data sources, the JasperFillManager gets stuck and is not able to generate any PDFs. I have waited for around two hours, but there is no progress. The issue seems to occur at this line: 'JasperPrint jasperPrint = JasperFillManager.fillReport(templateStream, params);' Please note that I am using JDK 17 and Tibco 6.20.0 to compile reports, and XMLs as the data source without connecting to any database. Could someone please help?
