Bumps com.github.ben-manes.caffeine:caffeine from 2.9.3 to 3.0.0.

Release notes

Sourced from com.github.ben-manes.caffeine:caffeine's releases.

3.0.0

This release includes API incompatible changes.

Highlights

  • Java 11 or above is required
  • Java 8 users can continue to use version 2.x, which will be supported

API improvements

  • Added Policy.refreshes() for a snapshot of the in-flight refresh operations
  • CacheLoader and AsyncCacheLoader offer bulk factory methods
  • AsyncCacheLoader methods may now throw checked exceptions
  • Better usage of Checker Framework nullness annotations (#337)
  • LoadingCache.refresh now returns the in-flight future (#143)
  • Various unimplemented default methods are now abstract
  • Added LoadingCache.refreshAll convenience method
  • Bulk loads now receive a Set of keys (was Iterable)
  • More flexible generic bounds and type parameters

Implementation improvements

Incompatible changes

  • VarExpiration time-based puts now return the old value instead of a boolean result
  • Removed jandex resource as no longer utilized by Quarkus
  • Split Policy.Expiration into fixed and refresh interfaces

Deprecation removals

  • CacheWriter, SingleConsumerQueue, and UnsafeAccess
  • StatsCounter.recordEviction variations
  • CacheStats constructors

Notes

  • CacheWriter usages can be replaced by Map computations and Caffeine.evictionListener
  • For best performance Unsafe may be used if available, otherwise falls back to VarHandles
  • We will continue to support and maintain version 2.x for Java 8 users
Commits
  • be6ad63 add checkerframework javadoc link
  • a95ae26 Added snapshot view of in-flight refresh operations
  • 0d23987 misc improvements (javadoc, generics, build)

fix: update KubernetesFromConfigMapProcessor for Caffeine 3.x compati…
b609abe 
…bility

Replace async refresh() with synchronous put() and explicit invalidate()
for keys removed from ConfigMap. This fixes a race condition introduced
in Caffeine 3.x where asMap().get() returns null for expired entries
during an in-flight async refresh, causing KubernetesFromConfigMapTest
to fail intermittently.

Changes:
- Replace LoadingCache with Cache (CacheLoader no longer needed)
- Remove expireAfterWrite (entries managed explicitly by scheduler)
- Use put() to synchronously write ConfigMap data into cache
- Use invalidate() to remove keys no longer present in ConfigMap
- Remove ConfigMapGetterCacheLoader inner class

@copilot please fix CI/CD errors.

Fixed in commit 66dd19c.

The CI failures were in KubernetesFromConfigMapTest. The root cause was a behavioral change in Caffeine 3.x: asMap().get() no longer returns values for expired entries (stricter expiry vs. lazy eviction in 2.x). The previous code used expireAfterWrite(refreshInterval) with async refresh() at the same interval, creating a race window where entries expired while an async refresh was in-flight.

The fix in KubernetesFromConfigMapProcessor:

  • Replaced LoadingCache + async refresh() with Cache + synchronous put() — values are written atomically on each scheduler tick
  • Added explicit invalidate() for keys removed from the ConfigMap (replacing the expiry-based removal)
  • Removed expireAfterWrite and the now-unused ConfigMapGetterCacheLoader inner class
