同时使用多个线程调用下面的路由，当消息超时时，我得到一个死锁。有没有解决这个问题的方法？或者我错误配置了故障转移？故障转移负载均衡器中的死锁
我创建了一个简单的项目来演示该问题： https://github.com/leechinkong/CamelFailoverLoadbalancer
from("direct:test")
.loadBalance()
.failover(3, true, true)
.inOut("jms:testRqQueue1?replyTo=testRsQueue1&useMessageIDAsCorrelationID=true","jms:testRqQueue2?replyTo=testRsQueue2&useMessageIDAsCorrelationID=true");
