MessageProperties setDelay maximum value problem

[raylax]

Integer maximum value 2147483647
but the maximum value for rabbitmq-delayed-message-exchange is (2^32)-1=4294967295
Is it a bug or a feature?

spring-amqp/spring-amqp/src/main/java/org/springframework/amqp/core/MessageProperties.java

Line 454 in 7c94598

public void setDelay(Integer delay) {

So, you idea is to let this header to be set to that 4294967295 as maximum?
Since the Integer cannot be more than 2147483647, we probably need to change it to the Long and validate respectively.

Is that what you think?

Thanks

[raylax]

Yeah, I think that's right.
But would it be better to change it to Longor add a method like setDelayLong?

My English is not good, Sorry.

Yes, setDelayLong() is good compromise for the current version.
We may mark the integer one as @Deprecated and will consider to remove it in the next version.
