Bumps [com.cedarsoftware:java-util](https://github.com/jdereg/java-util) from 4.84.0 to 4.87.0. <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>4.87.0 - 2026-01-26</h4> <ul> <li><strong>BUILD</strong>: Version alignment with json-io 4.87.0 <ul> <li>Keeping java-util and json-io version numbers synchronized simplifies dependency management and ensures compatibility</li> </ul> </li> </ul> <h4>4.86.0 - 2025-01-26</h4> <ul> <li><strong>PERFORMANCE</strong>: <code>CompactMap</code> - Multiple optimizations reducing memory allocation and improving iteration performance <ul> <li>Fixed redundant <code>get()</code> call in <code>entrySet().contains()</code> - now reuses the result instead of calling both <code>get()</code> and <code>containsKey()</code></li> <li>Use <code>getCachedLegacyConstructed()</code> consistently in <code>switchBackingFromMapToArray()</code> instead of calling <code>getClass().getName().endsWith()</code></li> <li>Cache <code>CompactMapComparator</code> instances statically - 4 pre-created comparators for all combinations of case-insensitive and reverse ordering</li> <li>Added <code>isArraySorted()</code> check in <code>quickSort()</code> to skip unnecessary sorting during iteration (common case since binary insertion in <code>put()</code> maintains order)</li> </ul> </li> </ul> <h4>4.85.0 - 2025-01-24</h4> <ul> <li><strong>PERFORMANCE</strong>: <code>ClassUtilities</code> - Lock-free cache operations using CAS-based removal <ul> <li>Replaced synchronized blocks in <code>fromCache()</code>, <code>toCache()</code>, and <code>drainQueue()</code> with <code>ConcurrentHashMap.remove(key, value)</code></li> <li>CAS-based removal only removes if the exact WeakReference is still present, preventing race conditions</li> <li>Eliminates lock contention in high-throughput class loading scenarios</li> </ul> </li> <li><strong>PERFORMANCE</strong>: <code>ClassUtilities</code> - Added cache for assignable type lookups in <code>getArgForType()</code> <ul> <li>New <code>ASSIGNABLE_TYPE_CACHE</code> using <code>ClassValueMap<Optional<Supplier<Object>>></code> avoids repeated O(n) scans of <code>ASSIGNABLE_CLASS_MAPPING</code></li> <li>Uses <code>Optional</code> to distinguish "no match found" (<code>Optional.empty()</code>) from "not yet cached" (<code>null</code>)</li> <li>Improves constructor parameter resolution performance for repeated type lookups</li> </ul> </li> <li><strong>PERFORMANCE</strong>: <code>ClassUtilities</code> - Optimized synthetic parameter name detection <ul> <li>Added <code>isSyntheticArgName()</code> method using efficient string operations instead of regex</li> <li>Avoids <code>Pattern.matcher().matches()</code> overhead for checking "arg0", "arg1", etc. patterns</li> <li>Used in constructor parameter resolution to detect compiler-generated names</li> </ul> </li> <li><strong>PERFORMANCE</strong>: <code>DeepEquals</code> - Replace O(n²) visited set copying with O(1) ScopedSet for unordered collections <ul> <li>Previously, comparing unordered collections copied the entire visited set for each probe element (O(n × k))</li> <li>New <code>ScopedSet</code> wrapper creates a lightweight view with O(1) creation time</li> <li>Tracks local additions separately and discards them when probe completes</li> <li>Significant improvement for comparing large unordered collections/maps with cycles</li> </ul> </li> <li><strong>PERFORMANCE</strong>: <code>DeepEquals</code> - Multiple optimizations reducing per-comparison overhead <ul> <li>Replaced <code>ConcurrentSet</code> with <code>HashSet</code> for visited tracking - no concurrent access occurs</li> <li>Cache system properties at class load time instead of parsing on every call</li> <li>Simplified <code>hashCode()</code> by removing unnecessary <code>finalizeHash()</code> call</li> </ul> </li> <li><strong>IMPROVED</strong>: <code>ConcurrentNavigableSetNullSafe</code> - Changed sentinel from String to Object instance <ul> <li>Previous <code>"null_" + UUID.randomUUID()</code> String could theoretically collide with user data</li> <li>New <code>new Object()</code> sentinel is guaranteed unique and cannot collide</li> <li>Also changed from <code>.equals()</code> to identity comparison (<code>==</code>) for sentinel detection</li> </ul> </li> <li><strong>BUG FIX</strong>: <code>ClassValueMap</code> - Fixed <code>clear()</code> race condition that could leave permanently stale cache entries <ul> <li>Previous order: invalidate cache → clear backingMap (allowed concurrent <code>get()</code> to repopulate cache from still-populated backingMap)</li> <li>Fixed order: snapshot keys → clear backingMap → invalidate cache (ensures any <code>computeValue</code> after clear sees empty map)</li> <li>After <code>clear()</code> completes, all subsequent <code>get()</code> calls now see correct state</li> </ul> </li> <li><strong>BUG FIX</strong>: <code>ConcurrentNavigableMapNullSafe</code> - Fixed <code>ClassCastException</code> on sub-map views <ul> <li>Navigational methods (<code>lowerKey</code>, <code>floorKey</code>, <code>ceilingKey</code>, <code>higherKey</code>, etc.) incorrectly cast to <code>ConcurrentSkipListMap</code></li> <li>Sub-map, head-map, tail-map, and descending-map views are not <code>ConcurrentSkipListMap</code> instances</li> <li>Fixed by casting to <code>ConcurrentNavigableMap</code> instead (the interface that defines these methods)</li> </ul> </li> <li><strong>BUG FIX</strong>: <code>ConcurrentNavigableSetNullSafe</code> - Fixed user comparators that don't handle nulls throwing NPE <ul> <li>Comparators like <code>String.CASE_INSENSITIVE_ORDER</code> would throw NPE when comparing null elements</li> <li>Wrapper now gracefully falls back to default null ordering (nulls > non-nulls) if comparator throws NPE</li> <li>User comparators that handle nulls (via <code>Comparator.nullsFirst/nullsLast</code> or custom handling) still control null ordering</li> </ul> </li> <li><strong>BUILD</strong>: Updated json-io test dependency from 4.83.0 to 4.84.0</li> </ul> </blockquote> </details> <details> <summary>Commits</summary> <ul> <li><a href="https://github.com/jdereg/java-util/commit/60d880ffbbc0e5f8e413513b827f1f00b6573576";><code>60d880f</code></a> Bump version to 4.87.0</li> <li><a href="https://github.com/jdereg/java-util/commit/df4457f32988260a8ba6374fc13ec64670016c85";><code>df4457f</code></a> Update json-io test dependency to 4.85.0</li> <li><a href="https://github.com/jdereg/java-util/commit/fdda14259254977aafc90877a119be9e1bc2bffe";><code>fdda142</code></a> Bump version to 4.86.0</li> <li><a href="https://github.com/jdereg/java-util/commit/fab239f02711d832786608709fea6ddf74ca9043";><code>fab239f</code></a> Performance: CompactMap optimizations</li> <li><a href="https://github.com/jdereg/java-util/commit/81651cf28157b215475519e0b5bd83079308b419";><code>81651cf</code></a> Change Benefits and More Utilities headers to blue</li> <li><a href="https://github.com/jdereg/java-util/commit/b76c423c80ab11da36a5aaf87b02194fbd904737";><code>b76c423</code></a> Move java-util logo right, double left margin</li> <li><a href="https://github.com/jdereg/java-util/commit/1ef82953cd1ebe6139037eff4e2b883d9cb5bbf2";><code>1ef8295</code></a> Bump cache version to v=3</li> <li><a href="https://github.com/jdereg/java-util/commit/4580f535d46cfd36f7db1cc87fdcf90ab866ace9";><code>4580f53</code></a> Docs: Reduce vertical spacing, make infographic wider</li> <li><a href="https://github.com/jdereg/java-util/commit/ef2184688d09e0a4d1f267c617aa1e5b9d8f5679";><code>ef21846</code></a> Add cache-busting param to infographic URL</li> <li><a href="https://github.com/jdereg/java-util/commit/f4606450e71ca02b0113bdeae902bbaf6a6c3ce6";><code>f460645</code></a> Docs: Move hero infographic to top, remove badge logo</li> <li>Additional commits viewable in <a href="https://github.com/jdereg/java-util/compare/4.84.0...4.87.0";>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.
