DataSource/abandoned connection killer

MyHikariDataSource.java

public class MyHikariDataSource extends HikariDataSource{
  private final Timer killer = new Timer();

  public Connection getConnection() throws SQLException {
    final Connection c = super.getConnection();
    return (Connection) Proxy.newProxyInstance(getClass().getClassLoader(), new Class[] { Connection.class }, new MyHandler(c)));
  }

  private class MyHandler implements InvocationHandler {
    private Connection conn;
    private TimerTask killerTask;

    MyHandler(final Connection c) {
      this.conn = c;
      this.killerTask = new TimerTask() {
        public void run() {
          MyHikariDataSource.this.evictConnection(c);
          MyHandler.this.conn = null;
          MyHandler.this.killerTask = null;
        }
      }
    }

    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
      if (method.getName().equals("close")) {
        killerTask.cancel();
      }
      method.invoke(proxy, args);
    }
  }
}

Oops, I missed adding the killerTask to the killer Timer with some execution delay (deadline).
