-------------------------------------------------------------------------

Maven run successful, but running test from IDEA fails on compile stage. This is strange, I guess I need more investigation for this. Possibly IDEA compiles test differently from maven compiler. I'll post a bug to IDEA too.

> Static compiler incorrectly calculates type boundary for chain calls with generic types. When method is called, it takes boundary defined in the method of the class (Base in sample), instead of the boundary redefined in subclass (SubClass in sample).
> The bug was discovered when working with Lombok SuperBuilder generated classes from Groovy. The attached project demonstrate the bug on the smaller sample.
> Note that Java test infers type correctly, but groovy does not. However, the groovy test works when CompileStatic annotation is disabled.
> IDEA also shows red code here, but it possibly follows Groovy logic.
> The bug also affects earlier versions.
