IntegrationFlowContext

The IntegrationFlowContext is now an interface and IntegrationFlowRegistration is an inner interface of the IntegrationFlowContext.

Dispatcher Exceptions

Exceptions caught and re-thrown by AbstractDispatcher are now more consistent:

• A MessagingException of any kind, with a failedMessage property, is re-thrown unchanged
• All other exceptions are wrapped in a MessageDeliveryException with the failedMessage property set

Previously:

• A MessagingException of any kind, with a failedMessage property, was re-thrown unchanged
• A MessagingException, with no failedMessage property, was wrapped in a MessagingException with the failedMessage property set
• Other RuntimeException s were re-thrown unchanged
• Checked exceptions were wrapped in a MessageDeliveryException with the failedMessage property set

Integration Evaluation Context Bean

An integrationSimpleEvaluationContext bean for the SimpleEvaluationContext is register now alongside with the integrationEvaluationContext bean for the StandardEvaluationContext. Therefore an injection for the EvaluationContext should be reconsidered for the appropriate bean to use.
