Re: Exception starting karaf custom distro "minimal example" from docs

Hi Tom,

Here's a pom.xml to do what you want:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-Instance";

  <modelVersion>4.0.0</modelVersion>

  <groupId>example</groupId>
  <artifactId>my-karaf</artifactId>
  <version>1.0.0-SNAPSHOT</version>
  <packaging>karaf-assembly</packaging>

  <dependencies>
    <dependency>
      <groupId>org.apache.karaf.features</groupId>
      <artifactId>framework</artifactId>

    <dependency>

      <version>4.1.1</version>
      <classifier>features</classifier>
      <type>xml</type>
    </dependency>
  </dependencies>


  <build>
    <plugins>
      <plugin>

          <javase>1.8</javase>
        </configuration>
      </plugin>
    </plugins>
  </build>

</project>

It's what I used during ApacheCon to build a custom distribution of Karaf 
embedding Cellar (I removed the Cellar part for you).

I've attempted to build a simple custom Karaf distribution using the maven

I can build the assembly, but when I start the result I get an exception.

My pom configuration is currently very simple, just:

    <dependencies>
         <dependency>
             <groupId>org.apache.karaf.features</groupId>
             <artifactId>framework</artifactId>
             <version>${karafVersion}</version>

         </dependency>
         <dependency>
             <groupId>org.apache.karaf.features</groupId>
             <artifactId>standard</artifactId>
             <version>${karafVersion}</version>
             <classifier>features</classifier>
             <type>xml</type>
                        <scope>compile</scope>
         </dependency>

    ...

             <plugin>

                     <!-- <startupFeatures/> -->
                     <bootFeatures>
                         <!-- standard distribution -->
                         <feature>standard</feature>
                         <!-- minimal distribution -->
                         <!--<feature>minimal</feature>-->
                     </bootFeatures>
                     <javase>1.8</javase>
                 </configuration>
             </plugin>


karafVersion is 4.1.1

So I'm just bundling karaf, I'm not including anything else. This is the "minimal 
example" in the karaf docs.

On startup I get the log here : 
https://gist.github.com/tomq42/47403ec44413fdc517c70dc3cccbf0cb

I get the same if I specify "minimal" in "bootFeatures".
Am I doing something wrong here?

Thanks.
