Java 21 support for swagger-core?

I updated my application to support java 21. In that, all the javax.servlet.* imports were changed to jakarta. After this, I started seeing this error in swagger:
Failed to load API definition: response status is 500 /aps/openapi/openapi.json

The application logs are showing this error:
org.apache.catalina.core.StandardWrapperValve.invoke Allocate exception for servlet [OpenApi]
java.lang.ClassNotFoundException: javax.servlet.http.HttpServlet

Similarly, I updated my application to use jakarta.xml.bind-api version 4.0.2 (which was 2.3.5 previously)

I found that the latest release of swagger-core currently relies on jakarta.xml.bind-api=2.3.3. Reverting my application back to this dependency version and imports resolves the issue.

However, moving forward, my application requires these changes. Could you let me know if there are plans to provide support for java 21, or if there's an alternative approach that would allow this compatibility?

Start by reproducing the failure at /aps/openapi/openapi.json with Java 21 and the reported jakarta.xml.bind-api 4.0.2 dependency. Trace the OpenApi servlet failure and the javax.servlet.http.HttpServlet class loading error, then compare it with the working 2.3.5/2.3.3 dependency setup. Done means swagger-core supports the updated Jakarta dependencies without the 500 response.
