lhotari opened a new pull request, #21107:
URL: https://github.com/apache/pulsar/pull/21107
Fixes #21106
### Motivation
- Fix a bug in ConcurrentLongLongPairHashMap, ConcurrentLongPairSet and
ConcurrentOpenHashMap where the hash bucket's storage index was incorrectly
calculated.
- the impact of the bug has been that the implementations have been rather
unoptimal because of of frequent collisions in storing the item to the
underlying array. Essentially the hash bucket algorithm hasn't been properly
used.
### Modifications
- rename `bucket` to `bucketIndex` to indicate that it's the bucket index in
the storage array that needs to be calculated.
- calculate bucketIndex by multiplying the hash bucket by the item size (4
or 2).
