## Fixed Issues

<table><colgroup><col> <col></colgroup><thead><tr><th>Issue Resolution</th><th>ID</th></tr></thead><tbody><tr><td><p>Application properties configured in Runtime Manager are no longer cleared when you redeploy an application to on-premises servers by using <code>armDeployment</code>. The plugin now sends properties only when they’re defined in the plugin configuration.</p></td><td><p>W-24207441</p></td></tr><tr><td><p>The Mule Maven plugin now determines which Java versions are supported based on the <code>minMuleVersion</code> value declared in the <code>mule-artifact.json</code> file. The plugin uses this information to validate the <code>javaSpecificationVersions</code> value at build time.</p></td><td><p>W-24192837</p></td></tr><tr><td><p>The build now fails if <code>javaSpecificationVersions</code> in the <code>mule-artifact.json</code> file contains a Java version that the Mule version set in <code>minMuleVersion</code> doesn’t support. The plugin checks the Mule runtime engine support matrix, or a bundled copy for offline builds. To skip this validation, set <code>-DskipJavaVersionValidation=true</code>.</p></td><td><p>W-24192843</p></td></tr></tbody></table>
