-----------------------------
> Inherited methods with default parameters cause cause static compilation to
> fail
> --------------------------------------------------------------------------------
>
> Key: GROOVY-8405
> URL: https://issues.apache.org/jira/browse/GROOVY-8405
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 2.5.0-beta-1
> Reporter: Nathan Harvey
> Assignee: Daniel Sun
> Priority: Minor
> Fix For: 3.0.0-alpha-4, 2.5.3
>
>
> Given a super type with a method that has a default argument:
> {code}
> @CompileStatic
> class SuperType {
> void sample(String string, Integer arg=0) {}
> }
> {code}
> And a subclass that extends the method, but omits the optional parameters:
> {code}
> @CompileStatic
> class SubType extends SuperType {
> @Override
> void sample(String string) {}
> }
> {code}
> Static type checking fails to pick which method to call in the following code:
> {code}
> @CompileStatic
> class BrokenMethods {
> public static void main(String[] args) {
> new SubType().sample('hi')
> }
> }
> {code}
> The error message is:
> {code}
> Reference to method is ambiguous. Cannot choose between [void
> codes.nom.broken.SubType#sample(java.lang.String), void
> codes.nom.broken.SubType#sample(java.lang.String)]
> {code}
