Bumps [com.cedarsoftware:java-util](https://github.com/jdereg/java-util) from 4.72.0 to 4.80.0. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/jdereg/java-util/blob/master/changelog.md";>com.cedarsoftware:java-util's changelog</a>.</em></p> <blockquote> <h4>4.80.0 - 2025-01-05</h4> <ul> <li><strong>PERFORMANCE</strong>: Cache repeated <code>getClass()</code> calls in hot paths <ul> <li><code>ConcurrentNavigableMapNullSafe</code> - Cache <code>o1.getClass()</code> and <code>o2.getClass()</code> in comparator (6 calls → 2)</li> <li><code>CollectionUtilities</code> - Cache class lookups in deep copy operations for source, pair.source, and element objects</li> <li><code>GraphComparator</code> - Cache <code>srcValue.getClass()</code> and <code>targetValue.getClass()</code> in compare loop (7 calls → 2)</li> </ul> </li> <li><strong>PERFORMANCE</strong>: <code>ClassUtilities</code> and <code>GraphComparator</code> - Replace <code>isAssignableFrom(obj.getClass())</code> with <code>isInstance(obj)</code> <ul> <li><code>ClassUtilities.java:2278</code> - Constructor parameter type matching now uses <code>isInstance()</code></li> <li><code>GraphComparator.java:375</code> - Field type validation now uses <code>isInstance()</code></li> <li><code>isInstance()</code> avoids the <code>getClass()</code> call, providing better performance on hot paths</li> </ul> </li> <li><strong>FIX</strong>: <code>ClassUtilities</code> - Fixed unsafe mode reentrancy issue with counter-based ThreadLocal approach <ul> <li>Previously, nested <code>setUseUnsafe(true)</code>/<code>setUseUnsafe(false)</code> calls would incorrectly disable unsafe mode for outer callers</li> <li>Changed from <code>ThreadLocal<Boolean></code> to <code>ThreadLocal<Integer></code> counter (<code>unsafeDepth</code>)</li> <li><code>setUseUnsafe(true)</code> increments the counter, <code>setUseUnsafe(false)</code> decrements (but not below 0)</li> <li>Unsafe mode is active when counter > 0, supporting proper nesting</li> <li>Added comprehensive tests for nested calls, triple nesting, extra disables, and thread isolation</li> </ul> </li> <li><strong>FIX</strong>: <code>ThreadedLRUCacheStrategy</code> - Major concurrency fixes and architectural improvements: <ul> <li><strong>Architecture</strong>: Replaced per-instance ScheduledFutures with single shared cleanup thread for all cache instances. Uses WeakReference registry allowing unused caches to be garbage collected. Dead references pruned automatically during iteration.</li> <li><strong>Fix silent task death</strong>: Wrapped cleanup in try-catch to prevent ScheduledExecutorService from silently cancelling the task on exceptions.</li> <li><strong>Fix sort instability</strong>: Capture timestamps to array before sorting to prevent <code>IllegalArgumentException: Comparison method violates its general contract</code> caused by concurrent timestamp updates during sort.</li> <li><strong>Aggressive cleanup</strong>: When cache exceeds 10x capacity, removes all excess items immediately instead of batching.</li> </ul> </li> <li><strong>PERFORMANCE</strong>: <code>AbstractConcurrentNullSafeMap.computeIfAbsent()</code> - Added fast-path check before locking <ul> <li>Original implementation always called <code>compute()</code> which locks the bucket even for cache hits</li> <li>New implementation checks <code>get()</code> first - cache hits now bypass locking entirely</li> <li>Significant reduction in lock contention under concurrent load</li> </ul> </li> <li><strong>ADDED</strong>: <code>computeIfAbsent()</code> and <code>putIfAbsent()</code> support to LRU cache strategies <ul> <li><code>ThreadedLRUCacheStrategy</code> - atomic operations with timestamp updates</li> <li><code>LockingLRUCacheStrategy</code> - atomic operations with LRU reordering</li> <li><code>LRUCache</code> - delegation to underlying strategy</li> </ul> </li> </ul> </blockquote> </details> <details> <summary>Commits</summary> <ul> <li><a href="https://github.com/jdereg/java-util/commit/0a07c6950b942ec367828512505f5a74fa6309b7";><code>0a07c69</code></a> Prepare 4.80.0 release</li> <li><a href="https://github.com/jdereg/java-util/commit/6c1469547d7ac76cac333d550f7cfdabc4b2c698";><code>6c14695</code></a> Update changelog with ThreadedLRUCacheStrategy fixes</li> <li><a href="https://github.com/jdereg/java-util/commit/4b22f468799d0928c84606e139b68e42db3878d5";><code>4b22f46</code></a> Fix ThreadedLRUCacheStrategy concurrency issues and performance</li> <li><a href="https://github.com/jdereg/java-util/commit/59b654e6857eb1043146484a69083911c1a052b7";><code>59b654e</code></a> Update json-io test dependency to 4.72.0</li> <li><a href="https://github.com/jdereg/java-util/commit/4a6b88551261f67df8b67c7cf2dd078559905a0c";><code>4a6b885</code></a> Performance: Cache repeated getClass() calls in hot paths</li> <li><a href="https://github.com/jdereg/java-util/commit/47d469f6674c87bece20a0f3d6f8ae54f6efa01a";><code>47d469f</code></a> Update changelog with isInstance() performance optimizations</li> <li><a href="https://github.com/jdereg/java-util/commit/a0ae913f04b640b3ecab1ee576544341261436a8";><code>a0ae913</code></a> Performance and reliability improvements for ClassUtilities and GraphComparator</li> <li>See full diff in <a href="https://github.com/jdereg/java-util/compare/4.72.0...4.80.0";>compare view</a></li> </ul> </details> <br /> [](https://docs.github.com/en/github/managing-security-vulnerabilities/about-dependabot-security-updates#about-compatibility-scores) Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself.
