JUL TO SLF4J在TomEE 1.7.2上使用maven插件

我想在一个tomee maven项目中使用带有LOG4J2 impl的SLF4J api。因此，我加了我的pom.xml里面：JUL TO SLF4J在TomEE 1.7.2上使用maven插件

<dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-api</artifactId> 
     <version>1.7.12</version> 
    </dependency> 
    <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>jul-to-slf4j</artifactId> 
     <version>1.7.12</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.logging.log4j</groupId> 
     <artifactId>log4j-slf4j-impl</artifactId> 
     <version>2.4</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.logging.log4j</groupId> 
     <artifactId>log4j-api</artifactId> 
     <version>2.4</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.logging.log4j</groupId> 
     <artifactId>log4j-core</artifactId> 
     <version>2.4</version> 
    </dependency>

我编辑TomEE像这样的logging.properties文件：

handlers = org.slf4j.bridge.SLF4JBridgeHandler

我尝试使用此命令的Maven运行我的项目：

mvn package tomee:run

不幸的是我得到了一个例外：

objc[2756]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/bin/java and /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

我尝试添加依赖关系的lib：

<plugin> 
      <groupId>org.apache.openejb.maven</groupId> 
      <artifactId>tomee-maven-plugin</artifactId> 
      <configuration> 
       <context>ROOT</context> 
       <libs> 
        <li>org.slf4j:slf4j-api:1.7.12</li> 
        <lib>org.slf4j:jul-to-slf4j:1.7.12</lib> 
       </libs> 
      </configuration> 
     </plugin>

我可以Maven的控制台中看到：

[INFO] Copied 'org.slf4j:slf4j-api:1.7.12' in '/Users/xxx/Work/Git/xxx/target/apache-tomee/lib/slf4j-api-1.7.12.jar 
[INFO] Copied 'org.slf4j:jul-to-slf4j:1.7.12' in '/Users/xxx/Work/Git/xxx/target/apache-tomee/lib/jul-to-slf4j-1.7.12.jar

但我得到了同样的异常:(

一看07月到里面后， -slf4j-1.7.12.jar我可以看到org.slf4j.bridge.SLF4JBridgeHandler类文件存在。

我不明白为什么tomee找不到它？有没有可能mac的JDK bug有与此相关的东西？ objc[10012]: Class JavaLaunchHelper is implemented in both ... libinstrument.dylib. One of the two will be used. Which one is undefined

谢谢！

<li>org.slf4j:slf4j-api:1.7.12</li>

b在li标签内缺失。刚刚更新了lib
