Bumps [de.hs-heilbronn.mi:zlibsvm-core](https://github.com/rzo1/zlibsvm) from 2.1.2 to 3.0.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/rzo1/zlibsvm/releases";>de.hs-heilbronn.mi:zlibsvm-core's releases</a>.</em></p> <blockquote> <h2>zlibsvm-3.0.0</h2> <h1>Changelog</h1> <h2>3.0.0</h2> <h3>Breaking Changes</h3> <ul> <li><strong>Java 21 required</strong> — Minimum Java version raised from 17 to 21.</li> <li><strong><code>SvmTrainer.train()</code> now returns <code>Optional<SvmModel></code></strong> — Previously returned <code>null</code> when cross-validation mode was enabled. Callers must update from <code>model = trainer.train(docs)</code> to <code>model = trainer.train(docs).orElseThrow()</code> (or handle the empty case).</li> <li><strong><code>SvmMetaInformation</code> is now immutable</strong> — All 8 setter methods (<code>setSvmConfiguration</code>, <code>setNumberOfClasses</code>, <code>setAmountOfSupportVectors</code>, <code>setRhoConstants</code>, <code>setLabelForEachClass</code>, <code>setProbabilityA</code>, <code>setProbabilityB</code>, <code>setNumberOfSupportVectorsForEachClass</code>) have been removed from the interface and implementation. These were unused across the codebase.</li> <li><strong><code>NativeSvmModelWrapper</code> multi-arg constructors replaced by Builder</strong> — The 9- and 11-parameter constructors have been replaced with a fluent <code>NativeSvmModelWrapper.Builder</code>. The canonical <code>NativeSvmModelWrapper(svm_model)</code> constructor is unchanged.</li> <li><strong>Assertions replaced with <code>IllegalArgumentException</code></strong> — All <code>assert</code> statements in public API methods now throw <code>IllegalArgumentException</code> with descriptive messages. Code catching <code>AssertionError</code> from zlibsvm must catch <code>IllegalArgumentException</code> instead.</li> </ul> <h3>New Features</h3> <ul> <li><strong><code>SvmDocumentImpl</code></strong> — A ready-to-use <code>SvmDocument</code> implementation is now provided in <code>zlibsvm-core</code>, eliminating the need for users to write their own.</li> <li><strong>Cross-validation test coverage</strong> — New tests verify that cross-validation mode returns an empty <code>Optional</code> and produces meaningful accuracy values across different fold counts.</li> </ul> <h3>Bug Fixes</h3> <ul> <li><strong><code>SvmTrainingTestCase</code>: copy-paste errors</strong> — Test was comparing <code>getRhoConstants()</code> three times instead of validating <code>getProbabilityA()</code> and <code>getProbabilityB()</code>. A separate assertion was comparing a model's config to itself instead of the reference model.</li> <li><strong><code>SvmModelImpl</code>: incomplete config reconstruction</strong> — When loading models from native LIBSVM, only 6 of 16 configuration fields were reconstructed. Added <code>SvmConfigurationImpl.fromNativeParameter()</code> factory to capture all fields.</li> <li><strong><code>PrimitiveHelper</code>: array index safety</strong> — Map-to-array conversions used HashMap keys directly as array indices, risking <code>ArrayIndexOutOfBoundsException</code> with non-sequential keys. Now uses sorted iteration.</li> <li><strong><code>SvmConfigurationImpl</code>: mutable state exposure</strong> — <code>getWeight()</code> and <code>getWeightLabel()</code> returned mutable lists, allowing callers to corrupt the immutable configuration. Now wrapped in <code>Collections.unmodifiableList()</code>.</li> <li><strong><code>SvmPerformanceTestCase</code></strong>: <code>MODE_NAME</code> typo renamed to <code>MODEL_NAME</code>; <code>@BeforeEach</code> changed to <code>@BeforeAll</code> so the reference benchmark runs once per class instead of before every test.</li> </ul> <h3>Improvements</h3> <ul> <li><strong>Migrated to JUnit 5</strong> (Jupiter) from JUnit 4.</li> <li><strong>Comprehensive JavaDoc</strong> added across all public API interfaces, enums, and core implementations.</li> <li><strong>README reworked</strong> — Fixed broken code formatting in the prediction example, added Requirements section, improved structure.</li> </ul> <h3>Dependency Updates</h3> <ul> <li>JUnit: 4.13.2 → 5.12.1</li> <li>maven-surefire-plugin: 3.5.4 → 3.5.5</li> <li>maven-compiler-plugin updated</li> <li>log4j-slf4j2-impl: 2.25.1 → 2.25.3</li> <li>maven-javadoc-plugin: 3.11.3 → 3.12.0</li> <li>maven-source-plugin: 3.3.1 → 3.4.0</li> <li>forbiddenapis: 3.9 → 3.10</li> <li>license-maven-plugin: 2.6.0 → 2.7.1</li> <li>versions-maven-plugin: 2.19.0 → 2.21.0</li> <li>central-publishing-maven-plugin updated</li> <li>actions/checkout: 5.0.0 → 6.0.2</li> <li>actions/setup-java: 5.0.0 → 5.2.0</li> </ul> </blockquote> </details> <details> <summary>Commits</summary> <ul> <li><a href="https://github.com/rzo1/zlibsvm/commit/27b9fbcae6e6b37f30c5d3fcc73a8cb8e256e0cf";><code>27b9fbc</code></a> Release 3.0.0</li> <li><a href="https://github.com/rzo1/zlibsvm/commit/267ac0601b9783400a9ff342d80fb0df1cacd38b";><code>267ac06</code></a> Bump to 3.0.0-SNAPSHOT, require Java 21</li> <li><a href="https://github.com/rzo1/zlibsvm/commit/b5463485a142cf66e18448bdfa4a8015a07c9073";><code>b546348</code></a> Add test coverage for cross-validation training path</li> <li><a href="https://github.com/rzo1/zlibsvm/commit/dc767ecfbcda7e8e02b5899ac19617b4da25f30a";><code>dc767ec</code></a> Return Optional<SvmModel> from train() instead of null for CV mode</li> <li><a href="https://github.com/rzo1/zlibsvm/commit/37a701f06edbb9bcd3c852a423ec2f0aeeb4fd4e";><code>37a701f</code></a> Refactor NativeSvmModelWrapper to use Builder pattern</li> <li><a href="https://github.com/rzo1/zlibsvm/commit/75f5f0330c52835ce6bcd3ab005a4c5d4c26aeaf";><code>75f5f03</code></a> Make SvmMetaInformation immutable by removing unused setters</li> <li><a href="https://github.com/rzo1/zlibsvm/commit/9bf9859526eed2911ae4e8b6006c55510a3f12c2";><code>9bf9859</code></a> Replace test mocks with SvmDocumentImpl in core domain</li> <li><a href="https://github.com/rzo1/zlibsvm/commit/90f8d0accf81489737bedece754080a6b147b003";><code>90f8d0a</code></a> Replace assert statements with IllegalArgumentException checks</li> <li><a href="https://github.com/rzo1/zlibsvm/commit/fbf56f779545c60423d6095b9e98d0a7d2ba5157";><code>fbf56f7</code></a> Fix mutable state exposure and broken Comparable contract</li> <li><a href="https://github.com/rzo1/zlibsvm/commit/a0e76082adddeb29c932e2d2827082fb6e9293dc";><code>a0e7608</code></a> Add *.model to .gitignore for generated test artifacts</li> <li>Additional commits viewable in <a href="https://github.com/rzo1/zlibsvm/compare/zlibsvm-2.1.2...zlibsvm-3.0.0";>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.
