Retry delays are tied to the lifetime of an import specification #43
Description
Since ImportSpecification creates the ExponentialBackoffExceptionHandler, the current retry delay is tied to the lifetime of the specification. That is, if an import fails five times and the same specification is used to import again, the next delay begins with the sixth attempt delay time instead of restarting from one.
Ideally the retry counter would restart at the beginning of a new import regardless of whether the specification is reused or not. However, this tends to be low impact bug because specifications are typically not reused. As a workaround, anyone encountering this issue can just create a new specification for each import instead of reusing specifications.
