>                 Key: GROOVY-9389
>                 URL: https://issues.apache.org/jira/browse/GROOVY-9389
>             Project: Groovy
>          Issue Type: Bug
>          Components: Static Type Checker
>    Affects Versions: 3.0.0
>            Reporter: Bjørn Mølgård Vester
>            Priority: Minor
>
> The following code works in Groovy 2.5.8 but fails compilation in 3.0.0:
> {code:java}
> @groovy.transform.CompileStatic
> class MyProp {
>     Integer myInt = 0
>     Integer getMyInt() { return myInt }    // Custom getter
>     void setMyInt(Integer i) { myInt = i } // Custom setter
> }
> @groovy.transform.CompileStatic
> class BugInGroovy300 {
>     static void main() {
>         new MyProp().myInt++ // This line cannot compile in Groovy 3.0.0
>     }
> }
> {code}
> The error is:
> {noformat}
> [Static type checking] - Cannot find matching method java.lang.Object#next(). Please check if the declared type is correct and if the method exists.
>  @ line 13, column 21.
>            new MyProp().myInt++ // This line cannot compile in Groovy 3.0.0{noformat}
> If using the decrement operator (--), the type checker looks for a "#previous()" method instead.
> The code works in 3.0.0 if using CompileDynamic instead. Relying on the generated accessor methods by Groovy also works.
