java.lang.OutOfMemoryError after upgrading to 3.16.5 (LocalCachedMap)

Expected behavior no OutOfMemoryError on applications using the same Redis server but the previous version of redisson 3.16.3

Actual behavior applications starting to OOM running version 3.16.3 while an application running with 3.16.5 was fine

Steps to reproduce or test case access the same Redis server with different versions of the library (3.16.3 vs. 3.16.5)

Redis version 5.0.3

Redisson version 3.16.3 and 3.16.5

Redisson configuration local cache map config

    @Nonnull
    @Override
    public <T extends RedisCacheable> RedisWithLocalCache<String, T> getLocallyCachedMap(@Nonnull final CacheKey cacheName,
            final int cacheSize,
            @Nonnull final Duration timeToLive,
            @Nonnull final Duration localCacheTimeToLive) {
        final var options = LocalCachedMapOptions.<String, T> defaults() //
                .cacheSize(cacheSize) //
                .timeToLive(timeToLive.toMillis()) //
                .maxIdle(localCacheTimeToLive.toMillis()) //
                .evictionPolicy(LocalCachedMapOptions.EvictionPolicy.LRU) //
                .reconnectionStrategy(LocalCachedMapOptions.ReconnectionStrategy.LOAD) //
                .syncStrategy(LocalCachedMapOptions.SyncStrategy.UPDATE) //
                .writeMode(MapOptions.WriteMode.WRITE_BEHIND);
        return new RedisWithLocalCacheWrapper<>(redisson.getLocalCachedMap(cacheName.keyName(), options));
    }

I guess there is a compatibility issue caused by fix of https://github.com/redisson/redisson/issues/3978 Please upgrade to 3.16.5 version.
