Spring integration deadlock using Aggregator + MessageStoreReaper + Redis? - redis

Question

This question is related to this post in SI forum, but as the forum is closed, I post it here to continue the thread:
http://forum.spring.io/forum/spring-projects/integration/748192-messages-not-flowing-when-using-jms-channels
To sum up, I have an aggregator with a Redis message store and a reaper scheduled every 60 secs. Messages are sent to the aggregator using a JMS-Channel. Here's the config:
<bean id="jedisPoolConfigBean" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxActive" value="10" />
<property name="maxIdle" value="5" />
<property name="minIdle" value="1" />
<property name="testOnBorrow" value="true" />
<property name="testOnReturn" value="true" />
<property name="testWhileIdle" value="true" />
</bean>
<bean id="loyaltyRedisConnectionFactory"
class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<property name="hostName" value="${redis.hostName}" />
<property name="database" value="${redis.loyalty.database}" />
<property name="port" value="${redis.port}" />
<property name="poolConfig" ref="jedisPoolConfigBean" />
</bean>
<bean id="loyaltyAggregatorRedisMessageStore"
class="org.springframework.integration.redis.store.RedisMessageStore">
<constructor-arg ref="loyaltyRedisConnectionFactory" />
</bean>
<task:scheduler id="loyaltyScheduler"
pool-size="${loyalty.aggregator.reaper.pool_size}"/>
<task:scheduled-tasks scheduler="loyaltyScheduler">
<task:scheduled ref="loyaltyReaperBean" method="run" fixed-rate="60000" />
</task:scheduled-tasks>
<bean id="loyaltyReaperBean" class="org.springframework.integration.store.MessageGroupStoreReaper">
<property name="messageGroupStore" ref="loyaltyAggregatorRedisMessageStore" />
<property name="timeout" value="30000" />
</bean>
I'm a bit new with thread dumps but as far I can see DefaultMessageListener threads are stucked by the taskScheduler that launches the MessageReaper. In particular, at the ReentrantLock class.
Any idea? Maybe I have to make some other config to avoid this
Any help is appreciated
Thanks in advance!
