> Current implementation of needToCleanupState in
> KeyedProcessFunctionWithCleanupState actually has potention bug:
> {code:java}
> protected Boolean needToCleanupState(Long timestamp) throws IOException {
> if (stateCleaningEnabled) {
> Long cleanupTime = cleanupTimeState.value();
> // check that the triggered timer is the last registered processing
> time timer.
> return null != cleanupTime && timestamp == cleanupTime;
> } else {
> return false;
> }
> }
> {code}
> Please note that it directly use "==" to judge whether *Long* type timestamp
> and cleanupTime equals. However, if that value is larger than 127L, the
> result would actually return false instead of wanted true.
