+
+# Updating JVM Versions
+
+Updates the bundled JVM versions in `bin/docker-setup.sh` using Eclipse Temurin end-of-life data.
+
+## Files
+
+- `bin/docker-setup.sh` - Contains the JVM version loop that pre-installs JDKs via Coursier
+
+## Workflow
+
+1. **Check current versions** in `bin/docker-setup.sh`:
+   ```bash
+   grep "JVM_VERSION" bin/docker-setup.sh
+   ```
+
+2. **Fetch Eclipse Temurin lifecycle data**:
+   ```bash
+   curl -s https://endoflife.date/api/v1/products/eclipse-temurin/ | jq '.result.releases'
+   ```
+
+3. **Identify active LTS versions** - Filter for `isLts: true` and `isEol: false`:
+   ```bash
+   curl -s https://endoflife.date/api/v1/products/eclipse-temurin/ | \
+     jq -r '.result.releases[] | select(.isLts == true and .isEol == false) | "\(.name) - EOL: \(.eolFrom)"'
+   ```
+
+4. **Update docker-setup.sh** - Edit the `JVM_VERSION` loop with current LTS versions
+
+## API Reference
+
+**Endpoint**: `https://endoflife.date/api/v1/products/eclipse-temurin/`
+
+**Key fields per release**:
+| Field | Description |
+|-------|-------------|
+| `name` | Major version (e.g., "21", "17", "11", "8") |
+| `isLts` | Whether this is a Long-Term Support release |
+| `isEol` | Whether security support has ended |
+| `eolFrom` | Date when EOL begins |
+| `isMaintained` | Whether actively receiving updates |
+| `latest.name` | Latest patch version available |
+
+## Guidelines
+
+- Only include **LTS versions** that are **not EOL** (`isLts: true` AND `isEol: false`)
+- Order versions from newest to oldest (e.g., `25 21 17 11 8`)
+- Drop versions once `isEol` becomes `true`
+- Consider adding new LTS versions when `isLts` and `isMaintained` are both `true`
