Unable to use Kotlin value classes as function arguments to functions in @Repository when having dependency to org.springframework:spring-tx on the classpath #31890

pwestlin · 2023-12-22T13:56:19Z

When upgrading to Spring Boot 3.2.1 (from 3.1.7) we encountered a bug that throws an exception saying "object is not an instance of declaring class".

After a lot of dogging we've found out that the excpeption only occured when we had org.springframework:spring-tx on the classpath.
Acutually, org.springframework:spring-tx is a transitive dependency from org.springframework:spring-jms that we are using.

Environment

Spring Framework Version: 6.1.2 (with spring-boot 3.2.1)
Kotlin Version: 1.9.22
JVM Version: 17

Code

build.gradle.kts

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    id("org.springframework.boot") version "3.2.1"
    id("io.spring.dependency-management") version "1.1.4"
    kotlin("jvm") version "1.9.22"
    kotlin("plugin.spring") version "1.9.22"
}

group = "se.lantmateriet.tacodus.orderhanteraremock"
version = "0.0.1-SNAPSHOT"

java {
    sourceCompatibility = JavaVersion.VERSION_17
}

repositories {
    mavenCentral()
}

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-webflux")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("io.projectreactor.kotlin:reactor-kotlin-extensions")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-reactor")
    implementation("org.apache.httpcomponents:httpclient:4.5.14")

    testImplementation("org.springframework.boot:spring-boot-starter-test")
    testImplementation("io.projectreactor:reactor-test")

    implementation("org.springframework:spring-tx")
}

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs += "-Xjsr305=strict"
        jvmTarget = "17"
    }
}

tasks.withType<Test> {
    useJUnitPlatform()
}

Application

@SpringBootApplication
class ValueClassBugApplication

fun main(args: Array<String>) {
    runApplication<ValueClassBugApplication>(*args)
}

@RestController
@RequestMapping(("/foo"))
class FooController(
    private val fooRepository: FooRepository
) {

    @GetMapping("")
    suspend fun foo() {
        fooRepository.doSomething(AValueClass("foo"))
    }
}

//@Service
@Repository
class FooRepository {
    suspend fun doSomething(aValueClass: AValueClass) {
        //
    }
}

@JvmInline
value class AValueClass(val value: String)

Start the application and make a GET request;

curl -i localhost:8080/foo

Expected behavior

Server returns 200

Actual Behavior

The server returns 500 and gets an internal server error with an stacktrace:

If I change @Repository to @Service it works as expected.

Can you please test with Spring Framework 6.1.3-SNAPSHOT?

pwestlin · 2023-12-22T16:57:55Z

Can you please test with Spring Framework 6.1.3-SNAPSHOT?

How do I accomplish that in a manageable way? :)
I've tried with Spring Boot 3.2.2-SNAPSHOT but that includes Spring 6.1.2, just like Spring Boot 3.2.1.

You can set spring-framework.version=6.1.3-SNAPSHOT in gradle.properties, and make sure snapshot maven repository is included.

	maven {
		url "https://repo.spring.io/snapshot"
	}

It works with spring-framework.version=6.1.3-SNAPSHOT.
