¿Solución correcta para que Java 10 se queje por el acceso de reflexión ilegal por jaxb-impl 2.3.0?

Question

Estamos pensando en actualizar un código heredado a Java 10. Como JAXB no es visible de manera predeterminada (EDITAR): y la solución adecuada a largo plazo no es evitar el síntoma utilizando varios indicadores JVM, sino corregirlo correctamente. He añadido este fragmento de código a mi 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>

Desafortunadamente, todavía hay una advertencia impresa en el inicio de stderr. Aparentemente esta no es la solución correcta.

¿Cuáles son las dependencias adecuadas para usar aquí para resolver este problema?

Answer 1

jaxb-ri runtime usa ClassLoader#defineClass / Unsafe#defineClass para hacer algunas modificaciones de bytecode en runtime para optimizar el rendimiento. ClassLoader#defineClass se prueba primero, lo que provoca la advertencia.

Esta optimización heredada se elimina por completo en jaxb-ri master (después de la versión 2.3.0, aún no se ha publicado).

Para deshabilitar esta optimización para 2.3.0, configure la propiedad del sistema com.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize .

Después de la próxima actualización de la versión jaxb-ri a la versión más reciente se eliminará la advertencia. El artefacto de jaxb-core se suspenderá a favor del soporte de JPMS. El pom correcto se verá como:

<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 desea intentarlo antes, puede elegir la última compilación promovida desde: https://maven.java.net/content/groups/promoted/org/glassfish/jaxb/jaxb-runtime/
