Docker version 1.8.1, build d12ea79
Your docs mention installing Java 7 on OSX, but this is irrelevant when running inside the docker container, no?

[lwc]

Any word on this?

Another user seems to be able to use docker with codegen successfully (the error message is related to the Swagger spec)

Ref: #1351

[goborrega]

I had the same problem when building in docker.
Had to change the pom.xml file (line 77) to add the -XX:+StartAttachListener parameter to the maven plugin

<plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>${surefire-version}</version>
                <configuration>
                    <testNGArtifactName>none:none</testNGArtifactName>
---->               <argLine>-XX:+StartAttachListener</argLine>**
                </configuration>

Seems to be related to a bug in the JDK (OSX only I think). More info here http://stackoverflow.com/questions/15245319/intermittent-junit-error-java-virtual-machine-connection-refused
