Inconsistent @Nullable on AbstractDestinationResolvingMessagingTemplate [SPR-15670]

[spring-projects-issues]

Gary Russell opened SPR-15670 and commented

In AbstractDestinationResolvingMessagingTemplate, some methods are missing @Nullable on MessagePostProcessor.

For example,

public <T> void convertAndSend(String destinationName, T payload, MessagePostProcessor postProcessor)

delegates to

public <T> void convertAndSend(String destinationName, T payload, @Nullable Map<String, Object> headers, @Nullable MessagePostProcessor postProcessor)

Also

public <T> T convertSendAndReceive(String destinationName, Object request, Class<T> targetClass,
			MessagePostProcessor postProcessor)

public <T> T convertSendAndReceive(String destinationName, Object request, Map<String, Object> headers,
			Class<T> targetClass, MessagePostProcessor postProcessor)

delegate to methods in the superclass that have @Nullable MessagePostProcessor postProcessor.
