Description
i'm trying to implement a base test class with the annotation @RunWith(CdiTestRunner.class) and provide some utility methods for tests.
to start a new request in a test method i'm using ContextControl to stop and start RequestContext and SessionContext.
here are my cdi-ctrl dependencies
<dependency>
<groupId>org.apache.deltaspike.cdictrl</groupId>
<artifactId>deltaspike-cdictrl-openejb</artifactId>
<version>${deltaspike.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.apache.tomee</groupId>
<artifactId>openejb-core</artifactId>
<version>7.0.2</version>
<scope>test</scope>
</dependency>
with one test everything works fine but as soon as i've more the call to contextControl.stopContext(RequestScoped.class) (or any other scope) blows up with an NPE

i've configured deltaspike.testcontrol.stop_container = false in src/test/resources/META-INF/apache-deltaspike.properties
when booting the container for each test class it works but my goal is to start the container only once for all test in my module since this takes some time for bigger modules 
don't know if the fix is as trivial as it looks but adding
if (cdiTestRunner == null || *cdiTestRunner.testContext.externalContainers == null*) { return Collections.emptyList(); }
fixes at least the NPE.
or is there anything else i’m doing wrong?
will upload a small sample but i'm currently on train and connection is really bad :/ so this can take some time
