问题描述
我正在尝试运行我创建的Java 9模块，该模块使用Log4j2 2.10.0。
I am trying to run a Java 9 module I've created which uses Log4j2 2.10.0.
我遇到的问题是我得到了一个
The problem I'm running into is that I get a
java.lang.NoClassDefFoundError: Could not initialize class org.apache.logging.log4j.util.PropertiesUtil
在执行 LogManager.getLogger（）时。它找到了LogManager类，但是当它从 StatusLogger 新的PropertiesUtil（log4j2.StatusLogger.properties）时c $ c>，它收到上述错误。
when doing a LogManager.getLogger(). It finds the LogManager class fine, but when it get to the new PropertiesUtil("log4j2.StatusLogger.properties") call from inside StatusLogger, it gets the above error.
如何修复/找到解决方法？
How do fix/find a workaround for this?
添加信息：
堆栈跟踪：
Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.apache.logging.log4j.util.PropertiesUtil
at org.apache.logging.log4j/org.apache.logging.log4j.status.StatusLogger.<clinit>(StatusLogger.java:71)
at org.apache.logging.log4j/org.apache.logging.log4j.LogManager.<clinit>(LogManager.java:60)
at com.EvolutionarySoftwareSystems.Utilities/com.EvolutionarySoftwareSystems.Utilities.Base.DebugAble.<clinit>(DebugAble.java:45)
我可以直接调用调用的一个奇怪的事情：我的代码中的新PropertiesUtil（string）它找到了class。
One more odd thing I can directly call the invoke: new PropertiesUtil("string") from my code and it finds the class.

推荐答案
Log4j有一个问题报告见 https://issues.apache.org/jira/browse/LOG4J2-2129 。
要么使用2.9，要么使用2.10和我在该故障单中提供的解决方法，或者使用2.11，这是在几天前发布并修复了问题。
Log4j has an issue there which is reported at https://issues.apache.org/jira/browse/LOG4J2-2129.
Either use 2.9, or use 2.10 with the workaround I provided in that ticket or use 2.11 which was released a couple of days ago and fixes the issue.
