Hello all and thanks in advance for this great tool,

I'm current using Java 1.8, Spring Boot 2.5.2 and JUnit 4.14.2.

After I migrated from mock-junit version 0.8.0 to 0.10.0, I started to get the following error when I try to start the mock:

        java.lang.IllegalStateException: cacheDir is null

In my test, I start/stop the mock using the @Before and @After annotation like this:

@Before
    public void setUp() {
        keycloakMock.start();
    }

    @After
    public void tearDown() {
        keycloakMock.stop();
    }

The mock is injected using the @Resource annotation:

@Resource
    private KeycloakMock keycloakMock;

Finally, I managed to fix this issue cleaning the Application Context after each test using @DirtiesContext(classMode = BEFORE_EACH_TEST_METHOD) at the beginning of my test class. However, using this method is resource intense and increases the execution time from 3 min to 12, so I had to keep using version 0.8.0.

The trouble is that the mock itself is currently not meant to be re-used once stop() has been called. It should work fine if the mock is static within the test class.

Can you explain a bit more on why you inject it rather than constructing it as a JUnit class rule (as described in the readme)?

If I use:

    @ClassRule
    public static KeycloakMockRule keycloakMock = new KeycloakMockRule();

instead of

    @Resource
    private KeycloakMock keycloakMock;

I get the following error:

And then I get a 401 during the test.

Hm, that's odd. It should work just like that. But I guess that's a side track. I acknowledge that re-using the mock should be possible, so I'll look into how to make this work.
