>                 Key: GROOVY-8938
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8938
>             Project: Groovy
>          Issue Type: Bug
>          Components: groovy-runtime
>    Affects Versions: 2.5.4
>            Reporter: Anton Pryamostanov
>            Priority: Critical
>
> Note: **this seems to be a quite major issue**, kindly look at this one with emphasis.
> Please see the below test case:
> SubClass extends the SuperClass and overrides the field "inheritedField".
> {code}
> class OtherClass {
>     String otherField
>     OtherClass(String otherField) {
>         this.otherField = otherField
>     }
>     String toString() {
>         return otherField
>     }
> }
> class SuperClass {
>     final OtherClass inheritedField = new OtherClass("Super Class String")
> }
> class SubClass extends SuperClass {
>     final OtherClass inheritedField = new OtherClass("Sub Class String")
> }
> SuperClass superClass = new SuperClass()
> SubClass subClass = new SubClass()
> assert subClass.inheritedField.toString() == "Sub Class String"
> {code}
> *Actual result*: assertion fails
> *Expected result*: assertion should pass
> *Note*: If "final" modifier is removed, assertion passes as expected.
> This seems an issue with final field caching.
> Assertion error text:
> {code}
> Assertion failed: 
> assert subClass.inheritedField.toString() == "Sub Class String"
>        |        |              |          |
>        |        |              |          false
>        |        |              'Super Class String'
>        |        Super Class String
>        SubClass@5b4b841f
> 	at ConsoleScript11.run(ConsoleScript11:18)
> {code}
