SyncCache<...>.invalidateAll() is not calling/triggering the method annotated with @CacheInvalidate(all = true)

[jonathanptew]

Expected Behavior

    @Inject
    SyncCache<ServiceWithCache> cache;

    @BeforeEach
    void each() {
        cache.invalidateAll();
    }

    @Test
    void singleItemIsCached() {
        final var cacheKey = "cacheKey";

        assertThat(serviceWithCache.getCacheSize()).isEqualTo(0);

        final var cachedValue = serviceWithCache.cachedGet(cacheKey);
...
    }

    @Test
    void multipleItemsAreCached() {
        final var items = 5;
        final var cacheKey = "cacheKey";

        assertThat(serviceWithCache.getCacheSize()).isEqualTo(0);
....
    }

In each test I expect that the number of entries in the internal cache object should be 0.

ServiceWithCacheExplictResetTest behaves as expected but doesn't use micronaut's cache invalidation

Actual Behaviour

cache.invalidateAll() doesn't trigger calls to reset()

    private final Map<String, String> cachedItems = new LinkedHashMap<>();
...

    @CacheInvalidate(all = true)
    public void reset() {
        cachedItems.clear();
    }

Steps To Reproduce

1. Pull https://github.com/jonathanptew/micronaut-cache-example/
2. Run tests
3. ServiceWithCacheInvalidateResetTest fails on subsequent tests where the size of the cache is > 0
4. ServiceWithCacheExplictResetTest behaves as expected
