Description
Interface methods are eligible for annotation with Spring's @Async. When a GatewayProxyFactoryBean is used to provide an implementation for such an interface and the @EnableAsync advice is applied in proxy mode, invocations of the service method throw a NullPointerException. The exception is not thrown if @EnableAsync is not applied, and hand-writing a wrapper implementation that autowires the message channel and sends a GenericMessage with the argument as the payload works correctly.
In this stack trace, handlePostback(PostbackObject postback) is declared on the PostbackHandler interface, and I used <int:gateway> to wire the method onto a message chain.
