I am trying to migrate an old server to Jersey 3.0.8.
Among other issues, I found this one when accessing the landing page of the server:
Type Exception Report
Message Error allocating a servlet instance
Description The server encountered an unexpected condition that prevented it from fulfilling the request.

While trying to solve it, I found that Jersey 3 uses the jakarta namespace to replace the javax one, so I replaced implementation("javax.servlet:javax.servlet-api:4.0.1") with implementation("jakarta.servlet:jakarta.servlet-api:6.0.0"). I also went trough the code and replaced all the imports of dependencies with the javax namespace to ones with jakarta. The only classes that I couldn't migrate were the ones accessing javax.imageio, as there seems to be no jakarta equivalent for them.
But then, when I try to run the server and access an endpoint, I get this error:
Type Exception Report
Message Error allocating a servlet instance
Description The server encountered an unexpected condition that prevented it from fulfilling the request.

The error is clearly about javax.servlet.ServletContext not being found.
When I add the javax.servlet import alongside the jakarta.servlet one, the original issue comes back.
Do you know of a way around this problem? Is it necessarily around the build configuration or could it be coming from a different place?
For context, I am trying to run this project using Tomcat Embedded and I am using Gradle for building it.
Any insights would be greatly appreciated.
