Yes, fixed these two comments.
> Improving tests coverage for org.apache.flink.streaming.api
> -----------------------------------------------------------
>
> Key: FLINK-2480
> URL: https://issues.apache.org/jira/browse/FLINK-2480
> Project: Flink
> Issue Type: Test
> Components: Streaming
> Affects Versions: 0.10
> Reporter: Huang Wei
> Fix For: 0.10
>
> Original Estimate: 504h
> Remaining Estimate: 504h
>
> The streaming API is quite a bit newer than the other code so it is not that
> well covered with tests.
