Description

Even when
@CompileStatic is present on the class, ShortTypeHandling.castToString() is applied to RHS of the expression when LHS is of type String.

I've attached a test class and the compilation result (compiled with groovyc 2.4.13. Versions 2.5.0-beta-2, 2.6.0-alpha-2, 3.0.0-alpha-1 yielded same results).
