anik120 opened a new issue #424: JVM issue on Minikube while running Sample.java integration using 0.2.0 release of Kamel binary
URL: https://github.com/apache/camel-k/issues/424
 
 
   I started by getting a minikube environment up and running by using `minikube start`. I then enabled the registry addon by using `minikube addons enable registry`.
   
   I then installed the operator into a namespace called operators by using `kamel install -n operators` which showed be the output "Camel K installed in namespace operators".
   
   Doing an `kubectl get pods -n operators` shows me that the operator is running :
   ```
   NAME                                           READY     STATUS    RESTARTS   AGE
   camel-k-operator-55445dc59c-6mhgq               1/1     Running       0       1h
   ```
   I then tried to run an integration using `kamel run examples/Sample.java` which was noticed by the operator: 
   
   ```
   $ kubectl logs camel-k-operator-55445dc59c-6mhgq  
   
   time="2019-02-12T02:30:00Z" level=info msg="Inform integrations about context ctx-bhh2va7ltpam33v5096g state change"
   {"level":"info","ts":1549938600.9991944,"logger":"controller_integration","msg":"Reconciling Integration","Request.Namespace":"operators","Request.Name":"sample"}
   time="2019-02-12T02:30:01Z" level=info msg="Apply trait: deployment"
   time="2019-02-12T02:30:01Z" level=info msg="Apply trait: owner"
   time="2019-02-12T02:30:01Z" level=info msg="Integration sample transitioning to state Deploying"
   {"level":"info","ts":1549938601.1018343,"logger":"controller_integration","msg":"Reconciling Integration","Request.Namespace":"operators","Request.Name":"sample"}
   ```
   I could also see that the integration pod was created but with an error: 
   
   ```
   $ kubectl get pods
   NAME                               READY     STATUS        RESTARTS   AGE
   camel-k-operator-55445dc59c-6mhgq   1/1       Running       0          1h
   sample-6c777c5bcd-2q7k5          0/1       CrashLoopBackOff   5          1h
   ```
   When I log the sample pod I see the following error: 
   
   ```
    $ kubectl logs sample-6c777c5bcd-2q7k5
