Rule: One statement per line

Looks good to me (didn't test it though), well done for the re-use of the generic check

However I believe it would be better to go for internationalization right away, and provide an example, as we do on the other plugin (and thereby really making it a first class plugin ).

Indeed Dinesh - I agree that we should improve names and descriptions. This wasn't done, because of lack of time

About internationalization - this might mean upgrade of minimal required version of Sonar, so with Freddy we decided to postpone this, however I'll give it a try before release.

Manually tested, could you just update the description with the following lines :

<p>
The following code snippet illustrates this rule :
</p>

<pre>
    this.firstParam = "something";this.secondParam = "somethingElse";     //NOK as there are two statements
</pre>

Done.

Manually tested !
