I manually tested it against a server without streaming support, and it doesn't fall back to polling. I don't know if it's the intended behavior but it does use the backup to load the initial state but it does not fetch from upstream. I double-checked, and it's not polling. I believe it should poll if streaming fails. |

Against a server that supports streaming:
The main difference with a server that doesn't support streaming is that the client will output: Which probably means the error is not handled (because disabling streaming works). |

About the changes
Now that we released a new version of Java SDK with streaming support we can also add an example.
Run it with UNLEASH_API_TOKEN=sandbox_token UNLEASH_API_URL=sandbox_url ./gradlew run
The example listens to streaming changes and prints flag status and received events.
Most of the PR is boilerplate for gradle copied from other examples. Actual change is 60 LOC
