How to use Pax Exam in server mode with multiple fuse instances starting in particular order ?

Issue

• While using Pax Exam in server mode and starting multiple fuse instances the order of invocation of each instance is not happening sequentially.
• For example, for the below code

@ClassRule
    public static PaxExamServer exam1 = new PaxExamServer(AMQFuseTestSetupSupport.class);

    @ClassRule
    public static PaxExamServer exam2 = new PaxExamServer(AMQ2FuseTestSetupSupport.class);

    @ClassRule
    public static PaxExamServer exam3 = new PaxExamServer(FedMBFuseTestSetupSupport.class);

    @ClassRule
    public static PaxExamServer exam4 = new PaxExamServer(MB2FuseTestSetupSupport.class);

    @ClassRule
    public static PaxExamServer exam5 = new PaxExamServer(OMSFuseTestSetupSupport.class);

    @ClassRule
    public static PaxExamServer exam6 = new PaxExamServer(TMSFuseTestSetupSupport.class);

    @ClassRule
    public static PaxExamServer exam7 = new PaxExamServer(WMSFuseTestSetupSupport.class);

• The fuse containers exam1, exam2 .. are not starting one after the other.
• Also for the unpackDirectory method as mentioned below in

karafDistributionConfiguration() is not working as expected if there are mutiple fuse instances 
                        .frameworkUrl(maven().groupId(getFuseGroupId()).artifactId(getFuseArtifactId()).version(getFuseVersion()).type("zip"))
                        .karafVersion(getKarafVersion())
                        .useDeployFolder(false)
                        .name("JBoss Fuse")
                        .unpackDirectory(new File(PropertyHandler.getPropertyValue("target/PaxExam/AMQ"))),

frameworkUrl(maven().groupId(getFuseGroupId()).artifactId(getFuseArtifactId()).version(getFuseVersion()).type("zip"))
                        .karafVersion(getKarafVersion())
                        .useDeployFolder(false)
                        .name("JBoss Fuse")
                        .unpackDirectory(new File(PropertyHandler.getPropertyValue("target/PaxExam/MB"))),

• The above code is not resulting in creating UUID named directory one in target/PaxExam/AMQ and other target/PaxExam/MB but once target/PaxExam/AMQ is created the second instance UUID named directory is also created target/PaxExam/AMQ but not in target/PaxExam/MB.
