Netbeans：意外异常
Netbeans: Unexpected Exception
我在我的电脑上安装了 Apache Netbeans。一切正常。但是第二天我想继续我的工作，但是从那以后我一直得到一个例外:
A java.lang.IllegalAccessError exception has occurred.
Please report this at https://issues.apache.org/jira/projects/NETBEANS/issues,
including a copy of your messages.log file as an attachment.
The messages.log file is located in your
C:\Users\svent\AppData\Roaming\NetBeans.0\var\log folder.
我有以下设置：
产品版本：Apache NetBeans IDE12.0
Java: 17; OpenJDK 64 位服务器虚拟机 17+35-2724
系统：Windows10 amd64
我试过卸载所有东西然后重新安装。我还尝试使用 Java 11 或 Java 14。我还尝试从 AppData 中的 netbeans 中删除 12.0 文件夹。但是 none 这有帮助。
这是确切的例外：
java.lang.IllegalAccessError: superclass access check failed: class org.netbeans.lib.nbjavac.services.CancelAbort (in unnamed module @0x6a51d5d0) cannot access class com.sun.tools.javac.util.Abort (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.util to unnamed module @0x6a51d5d0

我希望有人能帮我解决这个问题，因为我不知道该怎么办了。
您是 运行 NetBeans 12.0 和 JDK 17。这不是受支持的组合。
您有两个选择：
- 坚持使用 NetBeans 12.0，并改用 JDK 14。
- 坚持使用 JDK 17，改用 NetBeans 12.5。 （在这种情况下，您不需要先卸载 NetBeans 12.0。）
请参阅 NetBeans 12.0 and NetBeans 12.5 的发行说明，了解支持哪些 Java 版本的详细信息。
与此类似的问题在这里很常见，不幸的是，NetBeans 没有更好地主动防止使用不受支持的 JDKs。也就是说，在 NetBeans 防御中：
- 您发布的错误消息明确建议您参阅 NetBeans 日志文件 (
messages.log) 以获取更多信息。
- NetBeans 发行说明始终明确说明给定 NetBeans 版本支持哪些 Java 版本，不应做出任何假设。例如，对于 NetBeans 12.5，支持的版本是 "JDK LTS releases 8 and 11, with experimental support for JDK 17"。该信息很重要，因为它表明尽管 JDK 17 具有“实验性支持”，但不支持 JDK 12 到 JDK 16 版本。
