+# StreamPark JDK Upgrade Guide
+
+StreamPark 3.0 requires **JDK 11 or later** to run the Console process.
+
+## Console JDK vs Job JDK
+
+| Component | JDK requirement | Configuration |
+|-----------|-----------------|---------------|
+| StreamPark Console | **JDK 11+** | `JAVA_HOME` in `streampark-env.sh` or system environment |
+| Flink jobs | Depends on Flink version | `$FLINK_HOME/conf/flink-env.sh` → `JAVA_HOME` |
+| Spark jobs | Depends on Spark version | `$SPARK_HOME/conf/spark-env.sh` → `JAVA_HOME` |
+
+Upgrading the Console to JDK 11 **does not require** upgrading Flink/Spark cluster JDK at the same time.
+
+## Compatibility Matrix
+
+| Engine | Minimum job JDK | Recommended job JDK |
+|--------|-----------------|---------------------|
+| Flink 1.17–1.20 | 8 | 11 |
+| Flink 2.x | 11 | 11 or 17 |
+| Spark 3.5+ | 11 | 11 or 17 |
+
+## Upgrade Steps
+
+### 1. Standalone deployment
+
+1. Install JDK 11 (e.g. OpenJDK 11, Amazon Corretto 11).
+2. Set `JAVA_HOME` in `conf/streampark-env.sh`:
+   ```bash
+   export JAVA_HOME=/path/to/jdk-11
+   ```
+3. Restart Console:
+   ```bash
+   ./bin/streampark.sh restart
+   ```
+4. Verify:
+   ```bash
+   ./bin/streampark.sh status
+   java -version   # should show 11+
+   ```
+
+### 2. Docker deployment
+
+Official StreamPark Docker images from 3.0 onward use JDK 11 internally. Pull the latest image:
+
+```bash
+docker pull apache/streampark:latest
+```
+
+### 3. Build from source
+
+JDK 11+ is required to build StreamPark 3.0:
+
+```bash
+export JAVA_HOME=/path/to/jdk-11
+./build.sh
+```
+
+## JVM Options
+
+StreamPark enables the following JVM options by default (see `bin/jvm_opts.sh`):
+
+```
+--add-opens java.base/jdk.internal.loader=ALL-UNNAMED
+--add-opens jdk.zipfs/jdk.nio.zipfs=ALL-UNNAMED
+```
+
+These are required for dynamic classpath loading (Flink shims, user JARs). Do not remove them unless you know the impact.
+
+## Troubleshooting
+
+| Symptom | Cause | Fix |
+|---------|-------|-----|
+| `StreamPark requires JDK 11 or later` on start | Console running on JDK 8 | Upgrade `JAVA_HOME` to JDK 11+ |
+| `NoSuchFieldException: ucp` | Missing `--add-opens` | Ensure `jvm_opts.sh` is not overridden incorrectly |
+| `javax.annotation.PostConstruct` not found | Missing annotation API | Use StreamPark 3.0+ distribution (includes dependency) |
+| Hadoop/YARN connection issues on JDK 11 | Jersey classpath | Verify Hadoop 3.3.x; check Hadoop client compatibility |
