Proper fix for Java 10 complaining about illegal reflection access by jaxb-impl 2.3.0?
提问by Thorbj?rn Ravn Andersen
We are looking at upgrading some legacy code to Java 10. As JAXB is not visible by default (EDIT: and the proper long term solution is notto circumvent the symptom using various JVM flags, but fix it properly) I have added this snippet to my pom.xml:
我们正在考虑将一些遗留代码升级到 Java 10。由于默认情况下 JAXB 不可见（编辑：正确的长期解决方案不是使用各种 JVM 标志来规避症状，而是正确修复它）我已将此代码段添加到我的 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>

Unfortunately there is still a warning printed at startup to stderr. Apparently this is not the correct fix.
不幸的是，在启动时仍然向 stderr 打印警告。显然，这不是正确的解决方法。

What are the proper dependencies to use here to resolve this problem?
在这里使用什么正确的依赖项来解决这个问题？
采纳答案by Roman Grigoriadi
jaxb-ri runtime uses ClassLoader#defineClass / Unsafe#defineClassto do some bytecode modification in runtime to optimize performance. ClassLoader#defineClassis tried first which causes the warning.
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。
This legacy optimization is removed completely in jaxb-ri master (after 2.3.0, not released yet).
这个遗留优化在 jaxb-ri master（2.3.0 之后，尚未发布）中完全删除。
To disable this optimization for 2.3.0, set system property
com.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize.
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。
After next jaxb-ri release updating to newest version will remove the warning. jaxb-core artifact will be discontinued in favor for JPMS support. Correct pom will look like:
在下一个 jaxb-ri 版本更新到最新版本后将删除警告。jaxb-core 工件将停止支持 JPMS。正确的 pom 将如下所示：
##代码##If you wish to try early, you can pick latest promoted build from: https://maven.java.net/content/groups/promoted/org/glassfish/jaxb/jaxb-runtime/
如果您想尽早尝试，可以从以下位置选择最新的升级版本：https: //maven.java.net/content/groups/promoted/org/glassfish/jaxb/jaxb-runtime/

kudos to @Roman Grigoriadi , He was right, the updated 2.4 version fixes the warning issues. Just add the dependencies below to the pomfile
感谢@Roman Grigoriadi，他是对的，更新的 2.4 版本修复了警告问题。只需将下面的依赖项添加到pom文件中
