Description:
There is no synchronization when new element is added to `com.mysql.cj.xdevapi.ClientImpl.activeProtocols`

```
public Session com.mysql.cj.xdevapi.ClientImpl.getSession() {
    ...
    this.activeProtocols.add(new WeakReference<>(prot));
    SessionImpl sess = new SessionImpl(prot);
    return sess;
}
```
