    This block could be removed if we got rid of the zero-args constructor in `ProgramParametrizationException`.

> While testing Flink by running the {{./examples/streaming/SocketWindowWordCount.jar}}
example, I got the following error message:
> {code}
> ./bin/flink run ./examples/streaming/SocketWindowWordCount.jar 
> Cluster configuration: Standalone cluster with JobManager at /127.0.0.1:6123
> Using address 127.0.0.1:6123 to connect to JobManager.
> JobManager web interface address http://127.0.0.1:8081
> Starting execution of program
> No port specified. Please run 'SocketWindowWordCount --port <port>', where port
is the address of the text server
> To start a simple text server, run 'netcat -l <port>' and type the input text into
the command line
> ------------------------------------------------------------
>  The program finished with the following exception:
> org.apache.flink.client.program.ProgramInvocationException: The program didn't contain
Flink jobs. Perhaps you forgot to call execute() on the execution environment.

> I think the error message is misleading, because I tried executing a valid Flink job.
