Date Fri, 29 Jan 2016 16:48:01 GMT
Hi Greg-

can you confirm these dependencies for log4j?

  <dependencies>    <dependency>      <groupId>org.apache.logging.log4j</groupId>
     <artifactId>log4j-api</artifactId>      <version>2.5</version>
    </dependency>    <dependency>      <groupId>org.apache.logging.log4j</groupId>
     <artifactId>log4j-core</artifactId>      <version>2.5</version>
   </dependency>    <dependency>      <groupId>junit</groupId>   
  <artifactId>junit</artifactId>      <version>4.9</version>     
<scope>test</scope>    </dependency>  </dependencies>
Thanks!
Martin
