*We recommend Java 8, Java 11 or Java 17 for our Qoppa’s PDF library and component products for the following reasons:
- We prefer Java releases that are LTS (Long Term Support), as they remain the industry standard for several years. See Oracle roadmap. Java 8, Java 17 and Java 11 are LTS.
- PDF Studio, Qoppa’s advanced Desktop PDF editor built on top of jPDFEditor and used by thousands of end-users every day, was shipped for many versions with Java 8 and is now shipped with Java 17 as of PDF Studio version 22.
- Qoppa’s development team environment is Java 8.
