DelayExpression not working starting in 2.0.0

[Nivek770]

I am working on a Project with Kotlin and Springboot and have run into an issue with the delayExpression value in the @Backoff annotation. It seems like starting at version 2.0.0 any value set will be ignored and instead the default delay of 1000ms will be used.

This is an exerpt from my code:

<dependency>
        <groupId>org.springframework.retry</groupId>
	<artifactId>spring-retry</artifactId>
	<version>2.0.1</version>
</dependency>

@Retryable(
        maxAttemptsExpression = "3",
        backoff = Backoff(delayExpression = "100")
    )
fun myRetryableFunction() {
    //do something
}

As I said, instead of using a delay of 100ms, the default value of 1000ms is used. Simply downgrading the version to 1.3.4 or lower will fix this issue and the delayExpression will be used.

As a work around use Backoff(delayExpression = "#{100}").

/**
* An expression evaluating to the canonical backoff period. Used as an initial value
* in the exponential case, and as a minimum value in the uniform case. Overrides
* {@link #delay()}. Use {@code #{...}} for one-time evaluation during initialization,
* omit the delimiters for evaluation at runtime.
* @return the initial or canonical backoff period in milliseconds.
* @since 1.2
*/
String delayExpression() default "";

It looks like the runtime evaluation is broken somehow.

With 1.3.x, evaluation was always during initialization, regardless of whether delimiters were provided.
