SQL check error when using concatenated strings with Kotlin

Hello, 

I'm having this problem since the last update (182.4505.22) and and also on the latest EAP (183.2940.10) where SQL defined in a string concatenation throws a checker error while using Kotlin:

The error in the tooltip is "<set assignment> expected" for the first one, "<statement> expected, got 'parent_id'" and so on which I'm guessing is because it isn't taking into account the next part of the string concatenation.

The same works fine in java

I'm missing something? or is this a bug?
