Command line used for generation

			<plugin>
				<groupId>org.openapitools</groupId>
				<artifactId>openapi-generator-maven-plugin</artifactId>
				<version>4.0.0</version>
				<executions>
					<execution>

							<goal>generate</goal>
						</goals>
						<configuration>
							<inputSpec>${project.basedir}/src/main/resources/email-api.yaml</inputSpec>
							<generatorName>jaxrs-spec</generatorName>
							<configOptions>

							<output>${project.basedir}</output>
							<apiPackage>...</apiPackage>
							<modelPackage>...</modelPackage>
						</configuration>
					</execution>
				</executions>
			</plugin>

Steps to reproduce

Using maven to trigger the generation. While I believe this is something to do with generator itself instead of the maven plug-in.

Related issues/PRs

https://github.com/OpenAPITools/openapi-generator/issues/2689 I believe this is related but not same generator.

Suggest a fix

So far the generated code is like this

    @GET
    @Produces({ "application/json" })
    List<Product> listProducts(, @QueryParam("page")  @DefaultValue("0")   Integer page);

And it shall be like tihs

    @GET
    @Produces({ "application/json" })
    List<Product> listProducts(@CookieParam("debug") String debug, @QueryParam("page")  @DefaultValue("0")   Integer page);
