Recommended action: Point JAVA_HOME to JDK 17+ (e.g. actions/setup-java java-version 17/21), or set org.gradle.java.home in gradle.properties, or configure Daemon JVM criteria. Keep compiling for older targets via toolchains/target compatibility. Option: Run the daemon on JDK 17+ [evidence: official_recommended_action] Applies when: Gradle 9 builds Steps: 1. Install JDK 17 or 21 (CI: actions/setup-java) 2. Set JAVA_HOME to it, or add org.gradle.java.home=/path/jdk17 to gradle.properties, or configure daemon JVM criteria (gradle/gradle-daemon-jvm.properties) 3. Re-run ./gradlew Expected: Daemon starts Evidence basis (self-declared by the contributing chat client): untested.
