Bumps [com.cedarsoftware:java-util](https://github.com/jdereg/java-util) from 4.0.0 to 4.1.0. <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>4.1.0</h4> <blockquote> <ul> <li> <p><strong>FIXED</strong>: <code>ClassUtilities.setUseUnsafe()</code> is now thread-local instead of global, preventing race conditions in multi-threaded environments where concurrent threads need different unsafe mode settings</p> </li> <li> <p><strong>IMPROVED</strong>: <code>ClassUtilities</code> comprehensive improvements from GPT-5 review:</p> <p><strong>🔒 SECURITY FIXES:</strong></p> <ul> <li><strong>Enhanced class loading security with additional blocked prefixes</strong>: Added blocking for <code>jdk.nashorn.</code> package to prevent Nashorn JavaScript engine exploitation; added blocking for <code>java.lang.invoke.MethodHandles$Lookup</code> class which can open modules reflectively and bypass security boundaries</li> <li><strong>Added percent-encoded path traversal blocking</strong>: Enhanced resource path validation to block percent-encoded traversal sequences (%2e%2e, %2E%2E, etc.) before normalization; prevents bypass attempts using URL encoding</li> <li><strong>Enhanced resource path security</strong>: Added blocking of absolute Windows drive paths (e.g., "C:/...", "D:/...") in resource loading to prevent potential security issues</li> <li><strong>Enhanced security blocking</strong>: Added package-level blocking for <code>javax.script.*</code> to prevent loading of any class in that package</li> <li><strong>Added belt-and-suspenders alias security</strong>: addPermanentClassAlias() now validates classes through SecurityChecker.verifyClass() to prevent aliasing to blocked classes</li> <li><strong>Fixed security bypass in cache hits</strong>: Alias and cache hits now properly go through SecurityChecker.verifyClass() to prevent bypassing security checks</li> <li><strong>Updated Unsafe permission check</strong>: Replaced outdated "accessClassInPackage.sun.misc" permission with custom "com.cedarsoftware.util.enableUnsafe" permission appropriate for modern JDKs</li> <li><strong>Simplified resource path validation</strong>: Removed over-eager validation that blocked legitimate resources, focusing on actual security risks (.., null bytes, backslashes)</li> <li><strong>Improved validateResourcePath() precision</strong>: Made validation more precise - now only blocks null bytes, backslashes, and ".." path segments (not substrings), allowing legitimate filenames like "my..proto"</li> </ul> <p><strong>⚡ PERFORMANCE OPTIMIZATIONS:</strong></p> <ul> <li><strong>Optimized constructor matching performance</strong>: Eliminated redundant toArray() calls per constructor attempt by converting collection to array once</li> <li><strong>Optimized resource path validation</strong>: Replaced regex pattern matching with simple character checks, eliminating regex engine overhead</li> <li><strong>Optimized findClosest() performance</strong>: Pull distance map once from ClassHierarchyInfo to avoid repeated computeInheritanceDistance() calls</li> <li><strong>Optimized findLowestCommonSupertypesExcluding performance</strong>: Now iterates the smaller set when finding intersection</li> <li><strong>Optimized findInheritanceMatches hot path</strong>: Pre-cache ClassHierarchyInfo lookups for unique value classes</li> <li><strong>Optimized loadClass() string operations</strong>: Refactored JVM descriptor parsing to count brackets once upfront, reducing string churn</li> <li><strong>Optimized hot-path logging performance</strong>: Added isLoggable() guards to all varargs logging calls to prevent unnecessary array allocations</li> <li><strong>Optimized getParameters() calls</strong>: Cached constructor.getParameters() results to avoid repeated allocations</li> <li><strong>Optimized buffer creation</strong>: Cached zero-length ByteBuffer and CharBuffer instances to avoid repeated allocations</li> <li><strong>Optimized trySetAccessible caching</strong>: Fixed to actually use its accessibility cache, preventing repeated failed setAccessible() attempts</li> <li><strong>Added accessibility caching</strong>: Implemented caching for trySetAccessible using synchronized WeakHashMap for memory-safe caching</li> <li><strong>Prevented zombie cache entries</strong>: Implemented NamedWeakRef with ReferenceQueue to automatically clean up dead WeakReference entries</li> </ul> <p><strong>🐛 BUG FIXES:</strong></p> <ul> <li><strong>Fixed interface depth calculation</strong>: Changed ClassHierarchyInfo to use max BFS distance instead of superclass chain walking</li> <li><strong>Fixed tie-breaking for common supertypes</strong>: Changed findLowestCommonSupertypesExcluding to sort by sum of distances from both classes</li> <li><strong>Fixed JPMS SecurityException handling</strong>: Added proper exception handling for trySetAccessible calls under JPMS</li> <li><strong>Fixed nameToClass initialization inconsistency</strong>: Added "void" type to static initializer and included common aliases in clearCaches()</li> <li><strong>Fixed tie-breaker logic</strong>: Corrected shouldPreferNewCandidate() to properly prefer more specific types</li> <li><strong>Fixed areAllConstructorsPrivate() for implicit constructors</strong>: Method now correctly returns false for classes with no declared constructors</li> <li><strong>Fixed mutable buffer sharing</strong>: ByteBuffer, CharBuffer, and array default instances are now created fresh on each call</li> <li><strong>Fixed inner class construction</strong>: Inner class constructors with additional parameters beyond enclosing instance are now properly matched</li> <li><strong>Fixed varargs ArrayStoreException vulnerability</strong>: Added proper guards when packing values into varargs arrays</li> <li><strong>Fixed named-parameter gating</strong>: Constructor parameter name detection now checks ALL parameters have real names</li> <li><strong>Fixed Currency default creation</strong>: Currency.getInstance(Locale.getDefault()) now gracefully falls back to USD</li> <li><strong>Fixed generated-key Map ordering</strong>: Fixed bug where Maps with generated keys could inject nulls when keys had gaps</li> <li><strong>Fixed loadResourceAsBytes() leading slash handling</strong>: Added fallback to strip leading slash when ClassLoader.getResourceAsStream() fails</li> <li><strong>Fixed OSGi class loading consistency</strong>: OSGi framework classes now loaded using consistent classloader</li> <li><strong>Fixed ClassLoader key mismatch</strong>: Consistently resolve null ClassLoader to same instance</li> <li><strong>Fixed computeIfAbsent synchronization</strong>: Replaced non-synchronized computeIfAbsent with properly synchronized getLoaderCache()</li> <li><strong>Fixed off-by-one in class load depth</strong>: Now validates nextDepth instead of currentDepth</li> <li><strong>Fixed OSGi/JPMS classloader resolution</strong>: Simplified loadClass() to consistently use getClassLoader() method</li> <li><strong>Fixed permanent alias preservation</strong>: Split aliases into built-in and user maps so clearCaches() preserves user-added permanent aliases</li> </ul> </li> </ul> </blockquote> <!-- raw HTML omitted --> </blockquote> <p>...
