JCache hangs forever when getting value from cache with useScriptCache=true

[theigl]

Expected behavior

Getting a value from JCache works.

Actual behavior

Since Redisson 3.17.0, the get operation on a cache hangs forever if useScriptCache is set to true. It works until 3.16.8.

Steps to reproduce or test case

public class JCacheTest extends NoTxTestCase {

	private static final String CACHE_PROVIDER = JCachingProvider.class.getName();

	private static final int TTL = 5000;
	private static final int MAX_IDLE_TIME = 0;
	private static final String ANY_CACHE = "myCache";
	private static final String ANY_KEY = "anyKey";
	private static final String ANY_VALUE = "anyValue";

	@Inject
	private RedissonClient redissonClient;

	@Test
	void shouldGetCacheValue() {
		final Configuration<Object, Object> cfg = RedissonConfiguration.fromInstance(redissonClient,
				BaseCacheConfiguration.RedisCacheConfiguration.createConfiguration(new CacheConfig(TTL, MAX_IDLE_TIME)));
		final Cache<Object, Object> cache = createCache(ANY_CACHE, cfg);
		cache.put(ANY_KEY, ANY_VALUE);

		cache.get(ANY_KEY);
	}

	private static Cache<Object, Object> createCache(String cacheName, Configuration<Object, Object> configuration) {
		final CachingProvider p = Caching.getCachingProvider(CACHE_PROVIDER);
		final CacheManager cm = p.getCacheManager();
		return cm.createCache(cacheName, configuration);
	}
}

Redis version

4.0.10

Redisson version

3.17.0

Redisson configuration

	public RedissonClient createClient(Optional<EmbeddedRedisServer> embeddedRedisServer) {
		final Config cfg = new Config();
		cfg.setUseScriptCache(true);
		cfg.useSingleServer()
				.setAddress(this.redisAddress)
				.setPassword(Strings.emptyToNull(redisPassword));
		return Redisson.create(cfg);
	}

I have the same issue. In my case the first call to use the script hangs forever (using Reactor no signal is ever emitted). Subsequent calls work as expected. In my case I'm not using JCache, just a straight up call via Redisson.

Can you share some example code?

Fixed. Thanks for report
