Missing toString for ExponentialBackOff

The class ExponentialBackOff has its toString() method defined in the wrong place:

spring-framework/spring-core/src/main/java/org/springframework/util/backoff/ExponentialBackOff.java

Line 257 in 7e51193

public String toString() {

It is not defined for ExponentialBackOff itself, but for the inner class ExponentialBackOffExecution.

Thus, the following will print the hashCode instead of the nicely formatted output that was intended:

    System.out.println(new ExponentialBackoff(...))

instead of the nicely formatted output that was intended:

That's actually the right place, albeit perhaps the wrong prefix. You can't move that nice toString as it contains the interval and multiplier that are specific to the execution.

So there's a toString missing on ExponentialBackOff rather, and perhaps the existing toString should make it more clear it's about an execution.
