无法访问类 com.sun.org.apache.xerces.internal.impl.dv.util.Base64。

我有一个部署在Tomcat上的Web应用程序，当我尝试在NetBeans中部署它时，出现了这个错误。

java.lang.IllegalAccessError: class org.netbeans.modules.tomcat5.deploy.TomcatManagerImpl (in unnamed module @0x3196dd3d) cannot access class com.sun.org.apache.xerces.internal.impl.dv.util.Base64 (in module java.xml) because module java.xml does not export com.sun.org.apache.xerces.internal.impl.dv.util to unnamed module @0x3196dd3d

我该如何解决这个问题？我按照这些问题的步骤操作，但对我没有用。Java-xBased 部署问题.

OpenJDK 版本

openjdk 16 2021-03-16
OpenJDK Runtime Environment 21.3 (build 16+36)
OpenJDK 64-Bit Server VM 21.3 (build 16+36, mixed mode, sharing)

NetBeans 版本

除了其他问题外，使用JDK 16与NetBeans 12.0不是有效的。根据NetBeans 12.0的发布文档：_"Apache NetBeans 12.0可以在JDK LTS版本8和11上运行，也可以在JDK 14上运行，即在此NetBeans版本发布时的当前JDK版本"_. 因此，为解决此问题，请首先将JDK 14用作NetBeans 12.0上的默认平台，并在问题仍然存在时更新您的问题。 - skomisa
@skomisa 我想通了。 - SHARON XAVIER

那问题是什么？... - skomisa
@skomisa 这是一个 bug。 - SHARON XAVIER
好的。很好，你追求并解决了这个问题，尽管现在对你没有帮助。 - skomisa
@skomisa 我升级到了 NetBeans 12.3，现在出现了新的错误。请查看这个问题：https://stackoverflow.com/questions/67228369/can-not-clean-and-build-web-app-in-netbeans - SHARON XAVIER

Apache Netbeans 12.0需要JDK 14或更低版本才能正常工作，因此我建议安装Amazon Corretto 11或任何JDK 11发行版，并重新安装Apache Netbeans。
