The Jakarta EE Working Group has released the Jakarta EE 9.1 Platform and Web Profile specifications and related Technology Compatibility Kits (TCKs).

Jakarta EE 9.1 includes a number of updates and new options, and is compatible with Java SE 11. As a result, Java developers have more flexibility to mix and match technologies as needed to meet their unique application development and migration requirements. For example, they can:

  • Develop and deploy Jakarta EE 9.1 applications on Java SE 11, the most current LTS release of Java SE, as well as Java SE 8
  • Leverage Java SE 11 features that have been added since Java SE 8 in their Jakarta EE 9.1 applications
  • Leverage new technologies that support Java SE 11 in their Jakarta EE 9.1 applications
  • Migrate existing Jakarta EE 9 applications to Java SE 11 without changes
  • Migrate existing Java EE and Jakarta EE 8 applications to Jakarta EE 9.1 using the same straightforward process available for migration to Jakarta EE 9

Compatibility certifications with Jakarta EE 9.1 are already well underway, with five products certified as compatible with the release:

  • IBM’s Open Liberty
  • Eclipse Glassfish
  • Apache TomEE
  • Red Hat’s Wildfly
  • ManageCat’s ManageFish
