[GitHub] kafka pull request #3988: KAFKA-5967 Ineffective check of negative value in ...

KAFKA-5967 Ineffective check of negative value in CompositeReadOnlyKe…
package name: org.apache.kafka.streams.state.internals
Minor change to approximateNumEntries() method in CompositeReadOnlyKeyValueStore class.
long total = 0;
for (ReadOnlyKeyValueStore<K, V> store : stores) {
total += store.approximateNumEntries();
}
return total < 0 ? Long.MAX_VALUE : total;
The check for negative value seems to account for wrapping. However, wrapping can happen within the for loop. So the check should be performed inside the loop.
