Spring Potentially lose precision and jitter is not well capped

The jitter ratio calculation could throw an ArithmeticException if spec.delay().toMillis() returns 0. Additionally, converting to milliseconds may lose precision for sub-millisecond delays.

Retry retry = Retry.backoff(spec.maxAttempts(), spec.delay())
    .jitter((double) spec.jitter().toMillis() / spec.delay().toMillis())
    .multiplier(spec.multiplier())
    .maxBackoff(spec.maxDelay())
