Please don't expand the usage of these methods.
Awaitability should be used instead of this approach.

+1 - I think we should consolidate and only use Awaitility for these kinds of tests.

If we use Awaitility, then we need to use Fail-Fast Conditions feature.
But we need to upgrade the awaitility dependency to 4.1.0 or higher first. (Current Pulsar are using 4.0.3)
Example:
Awaitility.await().failFast(() -> {
Optional<Map<String, String>> cachedValue = objCache.getIfCached(key1);
// Need ensure objCache.getIfCached(key1) don't return a wrong value.
// Only retry when objCache.getIfCached(key1) return Optional.empty() or Optional.of(v)
return cachedValue.isPresent() && !Optional.of(v).equals(cachedValue);
}).untilAsserted(() -> assertEquals(objCache.getIfCached(key1), Optional.of(v)));@lhotari @michaeljmarshall Do you have a better idea when using the current version of awaitility? Thanks!

@Demogorgon314 A better approach would be to remove retryStrategically completely, as I did in #14518 (which didn't get merged since it was obsolete) |

There was a similar discussion about the desire to replace retryStrategically with Availability in #14373 (comment) . |
