Some notes

• Spec JSF 2.3: Section 5.9 "As of version 2.3 of this specification, JSF must run in a container that supports CDI version 2.0"
• When running on Glassfish 5 sometimes we can get a NPE which could be related to this issue

Migration:

• Changed imports from javax to jakarta
• Changed references from javax to jakarta in files: web.xml, Context.xml and jsf_messages.properties

Tested on:

• Java EE 8 (using refs javax)
• Jakarta EE 8 (using refs javax)
• Jakarta EE 9 (using refs jakarta)
• TomEE 8 (supports only Java EE 8 / Jakarta EE 8, use this branch to run)
