Description
While working on another change, I realized that the FunctionITCase.testInvalidUseOfTableFunction() tests throws a NullPointerException during execution.
This error is not visible, because TableEnvironmentImpl.executeInternal() does not wait for the final job status.
It submits the job using the job client (JobClient jobClient = execEnv.executeAsync(pipeline);), and it doesn't wait for the job to complete before returning a result.
This is the null pointer that is hidden:
