Java Code Bridge Client

One-liner

From repo root: npm run sdk:java

API

start() — connects, sends auth, waits for auth_success, then sends hello; keeps running with heartbeat + reconnect.
sendConsole(level, message)
sendError(message)
onControl(handler) — handle control_request and reply with control_result.
stop() — stops loop and closes socket.

Runtime behavior

Heartbeat: ping every 15s (configurable) and reconnect if no pong within 30s.
Reconnect: exponential backoff 1s→30s with jitter.
Buffering: queues up to 200 events, drop-oldest, emits one info drop-count notice after flush.
Control: handles control_request and responds with control_result.

Testing

Requires JDK 11+, Maven, and Node (for the protocol host).

cd java
mvn test

Tests use src/test/resources/ProtocolHost.js to validate handshake ordering, heartbeat timeout/reconnect, buffering drop notice, and control round-trip. CI runs in .github/workflows/lang-parity-php-swift.yml (Temurin 17); consider expanding to a multi-JDK matrix later.
