> Try to debug the code:
> {code}
> boolean boolVar = false; //line 15
> if (boolVar) { // set breakpoint here and step over //line 16
>     print "ok"; //line 17
> } // end of file //line 18
> {code}
> It steps over to the line with print even though it is not executed.
> Seems that compiler does not generate line info for the last block (line 18):
> {code}
