ChannelCachingConnectionProxy close

[wang007]

why CachingConnectionFactory allocatedConnections field clear only in the resetConnection method ？
if ChannelCachingConnectionProxy is not open, clear this in allocatedConnections field on the destroy method

Yes; I noticed that last week but decided it wasn't very important because the connection will be refreshed the next time it is used:

spring-amqp/spring-rabbit/src/main/java/org/springframework/amqp/rabbit/connection/CachingConnectionFactory.java

Lines 795 to 802 in 05472a5

	else if (!cachedConnection.isOpen()) {
	try {
	refreshProxyConnection(cachedConnection);
	}
	catch (Exception e) {
	this.idleConnections.addLast(cachedConnection);
	}
	}
