@dajac , thanks for your comments. Yes, you are right, I didn't make the if
condition correct. I've updated it to use a `hasGenerationReset` helper method:
```java
private boolean hasGenerationReset(Generation gen) {
// the member ID might not be reset for ILLEGAL_GENERATION error, so
only check generationID and protocol name here
return gen.generationId != Generation.NO_GENERATION.generationId &&
gen.protocolName == null;
}
```
Before this change, we can just do `if (generation.equals(NO_GENERATION))`,
to check if the generation object is reset or not, now, the check should check
for `generationID` and `protocolName` field only, because member Id might not
be reset for some cases.
Thank you.
