Review Comment:
@ffang thanks for looking into this, I think it would be better to not
tangle RetryStrategy with exchanges and thread locals, what I have in mind (but
need some time to flash out) is something along this lines:
- introduce new interface `PerInvocationFailoverStrategy` - that would
indicate that the strategy is stateful
```java
interface PerInvocationFailoverStrategy {
FailoverStrategy newStrategy(InvocationContext context, Exchange
exchange);
}
```
- store it in map the like `inProgress` does:
```
private ConcurrentHashMap<String, FailoverStrategy> inProgressStrategies
= new ConcurrentHashMap<>();
```
- introduce `getStrategy(String key)` method to actually retrieve
`FailoverStrategy` per invocation
- the `RetryStrategy` would implement `PerInvocationFailoverStrategy` and
return new fresh instance for each invocation
I think it should work, may be I am missing some details, but I believe it
will more maintainable solution, wdyt? Thanks again!
