Migration of Apache Felix sub-projects to support Jakarta Servlet API 6.x and OSGi Jakarta Servlet Whiteboard

Migrated 30 “Apache Felix” sub-projects to “Jakarta Servlet API 6.0” https://jakarta.ee/specifications/servlet/6.0/ and “Whiteboard Specification for Jakarta™ Servlet” https://docs.osgi.org/specification/osgi.cmpn/8.1.0/service.servlet.html, as required by multiple commercial projects being worked on.

This project included, among others:

• Upgrade and refactoring of 30 “Apache Felix” project sub-projects – including “Apache Felix HTTP”, “Apache Felix Health Checks”, “Apache Felix Webconsole”, and other – to support “Jakarta Servlet API 6.0” and “OSGi Jakarta Servlet Whiteboard”
• Upgrade of required dependencies to support “Jakarta Servlet API 6.0” – e.g. “Servlet Whiteboard API” (‘org.osgi.service.servlet’)
• Verification via both integration tests and as part of an actual project https://github.com/geckoprojects-org/org.gecko.graphql/pull/8
