> ---------------------------------------------------------------------------------------------------
>
> Key: GROOVY-11005
> URL: https://issues.apache.org/jira/browse/GROOVY-11005
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 3.0.17
> Reporter: Jason Garrett
> Assignee: Eric Milles
> Priority: Minor
>
> If a class's ancestors declare a default-visibility property and a getter for that property:
> {code:java}
> class HasProperty {
> Object foo
> Object getFoo() {
> return foo
> }
> } {code}
> Then the class, if it is CompileStatic, cannot set that property.
>
> This fails to compile:
> {code:java}
> import groovy.transform.CompileStatic
> @CompileStatic
> class SetsProperty extends HasProperty {
> void doStuff() {
> foo = "example"
> }
> } {code}
> Compiler output:
> {noformat}
> SetsProperty.groovy: 8: [Static type checking] - Cannot set read-only property: foo
> @ line 8, column 3.
> foo = "example"{noformat}
>
> It also fails to compile with "this.@":
> {code:java}
> import groovy.transform.CompileStatic
> @CompileStatic
> class SetsProperty extends HasProperty {
> void doStuff() {
> this.@foo = "example"
> }
> } {code}
> Results in:
> {noformat}
> SetsProperty.groovy: 8: [Static type checking] - The field HasProperty.foo is not accessible
> @ line 8, column 9.
> this.@foo = "example"{noformat}
>
> {{These do compile if the class is not CompileStatic, or if the property is explicitly declared "public".}}
