SonarJs analysis broken by a simple program

[yj0...@gmail.com]

In a very simple JavaScript:

function test() {
    var a, b;
    if (a > b) {
        if (a != b) {
        }
    }
}

When SonarJs 2.20.0.4207 analysis, will be broken with messages (I guess this is a bug?):

Hello David,

Thanks for your finding. Indeed SonarJS fails with such code. I explained the problem in the ticket SONARJS-999.

Moreover there is a ticket SONARJS-970 which should prevent project analysis from failing by skipping the file causing the problem.

After upgrade to SonarJS 3.0, SONARJS-970 resolved, thank you.

David, thanks for validation!
