Synchronization problem when resolving the channel

[FcoJavierSainz]

Hi, We are getting an strange error when we try to get a channel
Could not register object [org.springframework.integration.channel.DirectChannel@2898b3cc] under bean name 'topic_name': there is already object [topic_name]

I am using BinderAwareChannelResolver::resolveDestination(topicName)

Do you think we need to use a synchronized context there? Normally happens when we use concurrent threads at the beginning

@FcoJavierSainz Could be a concurrency issue - what version of the framework are you using?

[FcoJavierSainz]

Here is the SCS version

dependencyManagement {
     imports {
          mavenBom 'org.springframework.cloud:spring-cloud-stream-dependencies:Brooklyn.SR3'
     }
}

And here the dependencies, we override spring-integration-kafka

	compile 'org.springframework.integration:spring-integration-kafka:2.1.0.RELEASE'
	compile 'org.springframework.cloud:spring-cloud-stream'
	compile 'org.springframework.cloud:spring-cloud-starter-stream-kafka'
	compile('org.apache.kafka:kafka-clients:0.10.0.1') {
		exclude module: 'slf4j-log4j12'
	}

@mbogoevici see my comment in Gitter - we need to recheck the bean can't be resolved inside the synchronized block.
