[dependabot]

Bumps com.cedarsoftware:java-util from 4.70.0 to 4.72.0.

Changelog

Sourced from com.cedarsoftware:java-util's changelog.

4.72.0 - 2025-12-31

• BUG FIX: Fixed Jackson dependencies incorrectly declared without <scope>test</scope>. Jackson (jackson-databind, jackson-dataformat-xml) is only used for testing and should not be a transitive dependency. This restores java-util's zero external runtime dependencies.
• BUG FIX: Fixed ThreadedLRUCacheStrategy scheduled task accumulation. When CaseInsensitiveMap.replaceCache() was called multiple times, each new cache scheduled a purge task that was never cancelled. These orphaned tasks accumulated and could overwhelm the scheduler thread. Now:
  • ThreadedLRUCacheStrategy.shutdown() properly cancels the scheduled purge task
  • LRUCache.shutdown() delegates to the strategy's shutdown
  • CaseInsensitiveMap.replaceCache() calls shutdown on the old cache before replacing
• UPDATED: Test dependencies updated to latest versions:
  • jackson-databind: 2.17.2 → 2.20.1
  • jackson-dataformat-xml: 2.17.2 → 2.20.1

4.71.0 - 2025-12-31

• PERFORMANCE: MultiKeyMap.expandAndHash() - Multiple optimizations for faster key processing:
  • Fast-path for common leaf types: Added early-exit check for common final types (String, Integer, Long, Double, Boolean, Short, Byte, Character, Float) using class identity comparison (==) instead of falling through the instanceof chain. Since these are the most frequent key types, checking them first skips the more expensive instanceof checks (Map, Set, Collection) for 80%+ of calls.
  • Array detection optimization: Replaced isArray() with getComponentType() != null for slight additional speedup.
  • Set allocation elimination: Eliminated per-element ArrayList allocation when processing Sets. Previously created N temporary ArrayLists and N addAll() calls for a Set with N elements. Now adds elements directly to result list.
  • Benchmark impact: 3 additional wins vs Apache Commons MultiKeyMap (29 wins vs 26 before), converting ties to wins with no new losses.
• PERFORMANCE: MultiKeyMap.keysMatch() - Removed redundant conditional check where both branches performed identical operations.
• PERFORMANCE: Converter.getInheritedConverter() - Added caching for inheritance pairs:
  • cacheCompleteHierarchy: Caches full type hierarchy including level 0
  • cacheInheritancePairs: Uses MultiKeyMap to cache sorted pairs per (source, target)
  • InheritancePair class: Holds cached pair data without instanceId
  • First call for each (source, target) pair builds and caches the sorted pairs. Subsequent calls use O(1) cache lookup + iteration over pre-sorted list.
• IMPROVED: Converter.getSupportedConversions() and allSupportedConversions() - Now correctly report all dynamic container conversions:
  • Array/Collection conversions: Object[] ↔ Collection, array to array
  • Enum conversions: Array/Collection/Map to Enum (creates EnumSet), EnumSet to Collection/Object[]
  • isConversionSupportedFor(): Added optimistic handling for Object[] source component type - returns true when source component is Object.class (can't know actual element types at compile time)
• CLEANUP: FastReader - Removed unused extended API methods that were never utilized by json-io:
  • Deprecated: getLine() and getCol() now return 0 (line/column tracking removed for performance)
  • Removed line/column tracking overhead from hot path
  • getLastSnippet() provides error context without per-character tracking cost
