Bumps [com.cedarsoftware:java-util](https://github.com/jdereg/java-util) from 4.99.0 to 4.100.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/jdereg/java-util/releases";>com.cedarsoftware:java-util's releases</a>.</em></p> <blockquote> <h2>4.100.0</h2> <h2>What's Changed</h2> <ul> <li> <p><strong>BUG FIX</strong>: Fixed unbounded memory leak in <code>Converter.FULL_CONVERSION_CACHE</code>. Each short-lived <code>Converter</code> instance (e.g., one per <code>JsonIo.toJava()</code> call) cached inheritance-resolved conversions keyed by its unique <code>instanceId</code> in a static <code>ConcurrentHashMap</code>. When the instance was GC'd, its entries remained forever. In production under sustained load, this grew to 1GB+. Fix: cache resolved conversions at the shared level (<code>instanceId=0L</code>) when no user-added conversions exist; skip static caching otherwise. The cache is now bounded by the number of unique <code>(source, target)</code> type pairs, not by the number of <code>Converter</code> instances created.</p> </li> <li> <p><strong>PERFORMANCE</strong>: Optimized <code>Converter.getCachedConverter()</code> to skip the now-unnecessary instance-specific lookup, eliminating a wasted <code>ConversionPair</code> allocation per call.</p> </li> <li> <p>Updated test dependencies: JUnit 5.14.2→5.14.3, Jackson 2.21.1→2.21.2</p> </li> </ul> </blockquote> </details> <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>4.100.0 - 2026-04-10</h4> <ul> <li><strong>BUG FIX</strong>: Fixed unbounded memory leak in <code>Converter.FULL_CONVERSION_CACHE</code>.
