Bumps [com.cedarsoftware:java-util](https://github.com/jdereg/java-util) from 4.81.0 to 4.83.0. <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>4.83.0 - 2025-01-18</h4> <ul> <li><strong>PERFORMANCE</strong>: <code>LRUCache</code> (THREADED strategy) - Major performance improvements reducing overhead from ~5x to ~1.4x vs ConcurrentHashMap <ul> <li>Replaced <code>System.nanoTime()</code> with logical clock (AtomicLong counter) for LRU ordering - ~5ns vs ~25ns per operation</li> <li>Simplified probabilistic timestamp updates using timestamp low bits - eliminates atomic/ThreadLocal operations on most accesses</li> <li>Removed extra <code>get()</code> call in <code>put()</code> since Node creation is now cheap with logical clock</li> <li>Added amortized eviction (batch every 16 inserts) to spread eviction cost across operations</li> </ul> </li> <li><strong>BUG FIX</strong>: <code>LRUCache</code> - Fixed hard cap enforcement to guarantee memory bounds under high-throughput scenarios <ul> <li>Split eviction into <code>tryEvict()</code> (skippable) and <code>forceEvict()</code> (blocks until complete)</li> <li>Hard cap (2x capacity) now uses <code>LockSupport.parkNanos(1000)</code> for efficient spinning with low CPU usage</li> <li>Fixes issue where rapid inserts could exceed memory bounds when eviction couldn't keep up</li> </ul> </li> <li><strong>CHANGE</strong>: <code>CaseInsensitiveMap</code> - Default cache changed from <code>ConcurrentHashMap</code> to <code>LRUCache</code> (THREADED strategy) <ul> <li>Provides true LRU eviction (hot entries preserved) vs random eviction with ConcurrentHashMap</li> <li>Guarantees bounded memory (max 2x capacity) vs loose bounds with ConcurrentHashMap</li> <li>Performance is equivalent or better in benchmarks</li> <li>Users can still use <code>replaceCache()</code> to configure ConcurrentHashMap if desired</li> </ul> </li> </ul> <h4>4.82.0 - 2025-01-17</h4> <ul> <li><strong>BUG FIX</strong>: <code>TypeUtilities</code> - Fixed WildcardType bounds array mutation bug <ul> <li>External <code>WildcardType</code> implementations return internal arrays from <code>getUpperBounds()</code>/<code>getLowerBounds()</code></li> <li>These arrays were being modified in-place during resolution, corrupting the original type</li> <li>Fix: Clone arrays from external implementations before modification; skip cloning for internal <code>WildcardTypeImpl</code></li> </ul> </li> <li><strong>BUG FIX</strong>: <code>TypeUtilities</code> - Fixed unsafe cast for method-level TypeVariables <ul> <li><code>TypeVariable</code> can be declared on <code>Method</code> or <code>Constructor</code>, not just <code>Class</code></li> <li>Casting <code>getGenericDeclaration()</code> to <code>Class</code> would throw <code>ClassCastException</code> for method-level type variables</li> <li>Fix: Check declaration type and return first bound for non-class type variables</li> </ul> </li> <li><strong>PERFORMANCE</strong>: <code>TypeUtilities</code> - Added array class cache to avoid repeated <code>Array.newInstance()</code> allocations in <code>getRawClass()</code></li> <li><strong>PERFORMANCE</strong>: <code>TypeUtilities</code> - Use <code>IdentitySet</code> instead of <code>HashSet</code> for cycle detection (reference equality is sufficient and faster)</li> <li><strong>IMPROVED</strong>: <code>TypeUtilities</code> - Simplified <code>hashCode()</code> implementations using standard <code>31 * result</code> pattern instead of <code>EncryptionUtilities.finalizeHash()</code></li> <li><strong>IMPROVED</strong>: <code>TypeUtilities.WildcardTypeImpl</code> - Constructor now takes ownership of arrays without cloning (internal class only)</li> <li><strong>IMPROVED</strong>: <code>DeepEquals</code> - Fixed Javadoc formatting using <code>{@code}</code> blocks for proper HTML rendering of generic types</li> <li><strong>DEPRECATED</strong>: <code>LRUCache(int capacity, int cleanupDelayMillis)</code> - The <code>cleanupDelayMillis</code> parameter is no longer used; use <code>LRUCache(int)</code> instead</li> <li><strong>BUILD</strong>: Added <code>@SuppressWarnings</code> annotations to eliminate compile warnings across multiple classes: <ul> <li><code>CaseInsensitiveMap</code>, <code>ClassUtilities</code>, <code>ConcurrentNavigableSetNullSafe</code>, <code>ConcurrentSet</code></li> <li><code>MultiKeyMap</code>, <code>ReflectionUtils</code>, <code>TTLCache</code>, <code>UrlUtilities</code>, <code>MapConversions</code></li> </ul> </li> <li><strong>BUILD</strong>: Removed unused regex timeout methods from <code>DateUtilities</code></li> <li><strong>BUILD</strong>: Cleaned up unused code in <code>ObjectConversions</code></li> <li><strong>PERFORMANCE</strong>: <code>MultiKeyMap</code> - Significant hot path optimizations using Class identity checks <ul> <li><code>valueHashCode()</code> - Reordered type checks to handle Integer/Long/Double first; uses Class identity (<code>==</code>) instead of <code>instanceof</code> for common types (55% CPU reduction in JFR profiling)</li> <li><code>computeElementHash()</code> - Added Class identity fast path for String/Integer/Long/Double, skipping 4+ instanceof checks for 75% of typical key elements</li> <li><code>flattenKey()</code> - Added fast path at method entry for String/Integer/Long/Double keys</li> <li><code>flattenObjectArrayN()</code> - Skip array/collection checks for known simple types</li> <li><code>isArrayOrCollection()</code> - Added Class identity short-circuit for common simple types</li> <li><strong>Result</strong>: Cedar MultiKeyMap win rate vs Apache Commons Collections improved from ~60% to ~71% in performance benchmarks, while providing thread-safety, null key/value support, unlimited key count, and value-based numeric equality that Apache lacks</li> </ul> </li> <li><strong>PERFORMANCE</strong>: <code>ClassValueSet</code> - Optimized with Class identity checks <ul> <li><code>contains()</code> and <code>remove()</code> now use <code>o.getClass() == Class.class</code> instead of <code>instanceof</code></li> <li><code>clear()</code> no longer creates unnecessary HashSet copy before invalidating cache</li> </ul> </li> <li><strong>NEW</strong>: <code>IdentitySet<T></code> - High-performance generic Set using object identity (<code>==</code>) instead of <code>equals()</code> <ul> <li>Lightweight replacement for <code>Collections.newSetFromMap(new IdentityHashMap<>())</code></li> <li>Extends <code>AbstractSet<T></code> and implements full <code>Set<T></code> interface including <code>iterator()</code></li> <li>Uses open addressing with linear probing for excellent cache locality</li> </ul> </li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...
