------------------------------------------------------------------

Here's a simple unit test to reproduce the deadlock:

{code}
public class DeadLockTest extends SingleCacheManagerTest {

   @Override
   protected EmbeddedCacheManager createCacheManager() throws Exception {
      ConfigurationBuilder cfg = getDefaultStandaloneCacheConfig(false);
      cfg.indexing().index(Index.ALL).addProperty("default.directory_provider", "infinispan");
      return TestCacheManagerFactory.createCacheManager(cfg);
   }

   @Test
   public void testInit() throws Exception {
      cacheManager.getCache();
      assertTrue(cacheManager.isRunning(DEFAULT_CACHE_NAME));
   }
}
{code}

Requirement: a {{ProgrammaticSearchMappingProvider}} should be on the META-INF/services/, so that a search factory will be created always with an entity.

> The InfinispanDirectoryProvider tries to start the metadata, data, and locking caches when it starts up, with {{DefaultCacheManager.startCaches()}}.
> However, when one of these caches (e.g. the metadata cache) starts, the {{LifecycleManager.cacheStarting()}}, which can then try to start the InfinispanDirectoryProvider again:
