Correctif pour Java 10 se plaindre d'un accès illégal à la réflexion par jaxb-impl 2.3.0?

Nous envisageons de mettre à niveau certains codes hérités vers Java 10. JAXB n’est pas visible par défaut (EDIT: et la solution à long terme appropriée est not pour contourner le symptôme en utilisant divers indicateurs JVM, mais corrigez-le correctement) J'ai ajouté cet extrait à mon pom.xml:

    <!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->
    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
    </dependency>
    <dependency>
        <groupId>com.Sun.xml.bind</groupId>
        <artifactId>jaxb-core</artifactId>
        <version>2.3.0</version>
    </dependency>
    <dependency>
        <groupId>com.Sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.0</version>
    </dependency>

Malheureusement, il y a toujours un avertissement imprimé au démarrage sur stderr. Apparemment, ce n'est pas la solution correcte.

Quelles sont les dépendances appropriées à utiliser ici pour résoudre ce problème?

le runtime jaxb-ri utilise ClassLoader#defineClass / Unsafe#defineClass pour effectuer des modifications de code intermédiaire au moment de l'exécution afin d'optimiser les performances. ClassLoader#defineClass est essayé en premier, ce qui provoque l'avertissement.

Cette optimisation héritée est supprimée complètement dans le maître jaxb-ri (après la version 2.3.0, pas encore publiée).

Pour désactiver cette optimisation pour la version 2.3.0, définissez la propriété système com.Sun.xml.bind.v2.bytecode.ClassTailor.noOptimize.

Après la prochaine version de jaxb-ri, la mise à jour vers la version la plus récente supprimera l’avertissement. l'artefact jaxb-core sera abandonné en faveur du support JPMS. Pom correct va ressembler à:

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.4.0</version> <!-- not released yet -->
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.4.0</version> <!-- not released yet -->
</dependency>

Si vous souhaitez essayer plus tôt, vous pouvez choisir la dernière version promue parmi: https://maven.Java.net/content/groups/promoted/org/glassfish/jaxb/jaxb-runtime/

bravo à @Roman Grigoriadi, il avait raison, la version 2.4 mise à jour corrige les problèmes d’avertissement. Ajoutez simplement les dépendances ci-dessous au fichier pom

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.4.0-b180830.0359</version>
</dependency>
<dependency>
  <groupId>org.glassfish.jaxb</groupId>
  <artifactId>jaxb-runtime</artifactId>
  <version>2.4.0-b180830.0438</version>
</dependency>
