Getting Class cast exception after upgrading Spring Integration version

I have a Spring Integration Application which polls for data from AS400 DB picks it and then after some modification transmit it to MQ.
It was running fine until I decided to upgrade Spring Integration version.
I am getting below error after upgrading from version - spring-integration-core-2.2.3.RELEASE to spring-integration-core-3.0.1.RELEASE.

Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [tcm-hosttrade-inbound-adapter.xml]; nested exception is java.lang.ClassCastException: org.springframework.beans.factory.config.RuntimeBeanReference cannot be cast to org.springframework.beans.factory.config.BeanDefinition

I checked the code of class - org.springframework.integration.config.xml.AbstractPollingInboundChannelAdapterParser I just found these 3 lines of code different from earlier version - 

String channelAdapterId = this.resolveId(element, adapterBuilder.getRawBeanDefinition(), parserContext);
        String sourceBeanName = channelAdapterId + ".source";
        parserContext.getRegistry().registerBeanDefinition(sourceBeanName, (BeanDefinition) source);

So error is because of this line - parserContext.getRegistry().registerBeanDefinition(sourceBeanName, (BeanDefinition) source);

How can I make this code working? Below are my beans which could be used for reference -
Inbound Channel Bean - 

  <inbound-channel-adapter id="inboundAdapter" 
            ref="readFromMessageStore"
            channel="inboundChannel" auto-startup="false" />

When upgrading to a new version, it is generally recommended to use the latest version in that line; I am intrigued as to why you selected 3.0.1 when the latest version in that line is 3.0.7. The current version is 4.1.5; see the project page for complete version information. Generally, point releases (3.0.2, 3.0.3 etc) contain just bug fixes. Also, please pay attention to the migration guides.

Yes, 3.0.1 version has the problem. It is resolved in 3.0.2 version. You can check this link for the details : https://jira.spring.io/browse/INT-3300.

A small summary from the page link:
