Description

Examine the YML at https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator/src/test/resources/3_0/java/jspecify.yaml which is used to generate the sample code at https://github.com/OpenAPITools/openapi-generator/tree/master/samples/client/petstore/java/native-jackson3-jspecify

Note that;

• The API defines both "dtParam, "dtQuery" and "dtCookie" as not required
• The generated package-info defines the package as NullMarked

@org.jspecify.annotations.NullMarked

• The generated ApiClient:

• Correctly marks the parameters to fooDtParamGetRequestCreation as @Nullable:

private ResponseSpec fooDtParamGetRequestCreation(java.time.@Nullable Instant dtParam, java.time.@Nullable Instant dtQuery, java.time.@Nullable Instant dtCookie) throws RestClientResponseException {

• Incorrectly does not mark the parameters to fooDtParamGet as @Nullable:

public Foo fooDtParamGet( java.time.Instant dtParam,  java.time.Instant dtQuery,  java.time.Instant dtCookie) throws RestClientResponseException {

• Incorrectly does not mark the parameters to fooDtParamGetWithHttpInfo as @Nullable:

public ResponseEntity<Foo> fooDtParamGetWithHttpInfo( java.time.Instant dtParam,  java.time.Instant dtQuery,  java.time.Instant dtCookie) throws RestClientResponseException {
