Multipart file upload not working after spring boot upgrade 3.1.4

Question

We have just upgraded to spring boot 3.1.4. As part of the upgrade we have replaced javax.* with jakarta.* but multipart file upload api is failing with below error. Any pointers?

2024-02-14T14:48:35.476+0530 [http-nio-8080-exec-1] ERROR org.glassfish.jersey.server.ServerRuntime$Responder - Error while closing the output stream in order to commit response.
org.glassfish.jersey.server.ContainerException: java.util.concurrent.ExecutionException: java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided
    at org.glassfish.jersey.servlet.internal.ResponseWriter.getResponseContext(ResponseWriter.java:278) ~[jersey-container-servlet-core-3.1.3.jar:?]```

Steps taken:

1. Added @MultipartConfig
2. application.properties already has these:

spring.servlet.multipart.enabled=true
spring.servlet.multipart.max-file-size=20MB
spring.servlet.multipart.max-request-size=20MB

controller:

import jakarta.servlet.http.HttpServletRequest;
import jakarta.ws.rs.*;
import jakarta.ws.rs.core.Context;
import jakarta.ws.rs.core.HttpHeaders;
import jakarta.ws.rs.core.MediaType;
import jakarta.ws.rs.core.Response;

    @POST
    @Path("/uploadFiles")
    @ApiOperation(value = "Upload Files")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces(MediaType.APPLICATION_JSON)
    public Response uploadFiles(@Context HttpServletRequest request,
                                @Context HttpHeaders headers) {
body}

Whenever I call request.getParts() I get the error mentioned above.
