> copy/pasted the tutorial from this page:
> [https://nightlies.apache.org/flink/flink-docs-release-1.14/docs/dev/python/datastream_tutorial/]
> into a new cell of a new notebook.
> called word_count(None, None)
> output cell was:
>  
> {code:java}
> Executing word_count example with default input data set.
> Use --input to specify file input.
> Printing result to stdout. Use --output to specify output path.
> Exception in thread Thread-22:
> Traceback (most recent call last):
>   File "E:\dev\Conda\envs\py38\lib\threading.py", line 932, in _bootstrap_inner

> In the command line where the notebook was started, the output of the job was printed:
>  
> {code:java}
> WARNING: All illegal access operations will be denied in a future release
> +I[To, 1]
> +I[be,, 1]
> etc.{code}
>  
> If not easily fixable, maybe a mention that this doesn't work well in notebooks could be useful, considering how prevalent an environment they are.
