正确修复Java 10抱怨jaxb-impl 2.3.0的非法reflection访问？

我们正在考虑将一些遗留代码升级到Java 10.由于JAXB默认不可见（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）我已将此片段添加到我的pom.xml：

  javax.xml.bind jaxb-api 2.3.0   com.sun.xml.bind jaxb-core 2.3.0   com.sun.xml.bind jaxb-impl 2.3.0  

不幸的是，在stderr启动时仍然会出现警告。 显然这不是正确的解决方案。

--illegal-access=debug的完整输出是：

在此处使用哪些正确的依赖项来解决此问题？

Answer 1

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

在jaxb-ri master中完全删除了这个遗留优化（在2.3.0之后，尚未发布）。

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

在下一个jaxb-ri发布更新到最新版本之后将删除警告。 jaxb-core工件将停止支持JPMS支持。 正确的pom看起来像：

  javax.xml.bind jaxb-api 2.4.0    org.glassfish.jaxb jaxb-runtime 2.4.0   

如果您希望尽早尝试，可以从以下url选择最新推出的版本： https ： //maven.java.net/content/groups/promoted/org/glassfish/jaxb/jaxb-runtime/
