正确的Java 10修复程序抱怨jaxb-impl 2.3.0的非法反射访问？

问题内容：

我们正在考虑将一些遗留代码升级到Java10。由于默认情况下不可见JAXB（编辑：并且适当的长期解决方案 不是
使用各种JVM标志来规避症状，而是正确地对其进行修复），我将此代码段添加到了我的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>

不幸的是，在启动时仍会向stderr打印警告。显然，这不是正确的解决方法。

解决此问题的适当依赖项是什么？


问题答案：

jaxb-ri运行时用于ClassLoader#defineClass / Unsafe#defineClass在运行时进行一些字节码修改以优化性能。ClassLoader#defineClass首先尝试导致警告。

jaxb-ri主站中已完全删除了此传统优化（在2.3.0之后，尚未发布）。

要为2.3.0禁用此优化，请设置系统属性 com.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize。

在下一个jaxb-ri版本发行之后，更新到最新版本将删除该警告。jaxb-core工件将停止使用，以支持JPMS。正确的pom如下所示：

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

如果您想尽早尝试，可以从以下网址中选择最新的升级版本：https : //maven.java.net/content/groups/promoted/org/glassfish/jaxb/jaxb-
runtime/
