>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler
>    Affects Versions: 5.0.7
>            Reporter: Octavia Togami
>            Assignee: Paul King
>            Priority: Major
>
> The following code in a `Repro.groovy` will cause the error:
> {code:groovy}
> abstract class ProviderSpec<T> {
>     abstract T someValue()
> }
> abstract class CollectionPropertySpec<C extends Collection<String>> extends 
> ProviderSpec<C> {
>     C someValue() { return null }
>     static class Nested<T> {
>         // This method is required to trigger the bug, for some reason.
>         void trigger(Optional<T> p) { p.map { it } }
>     }
> }
> class DefaultListPropertyTest extends CollectionPropertySpec<List<String>> {
> }
> {code}

> This worked fine in Groovy 4 and appears to be correct code as it compiles 
> under {{javac}} as well.
> This was shrunk from real code in Gradle, located at
