Krzysztof Sierszeń updated GROOVY-10583:
----------------------------------------
Description:
A declaration of:
{code:java}
def <R extends SyntaxNode, O extends Node> List<O> $$(Collection<? extends R>
input, Class<O> outputType = Node) {code}
yields (package FQ names omitted for brevity):
{code:java}
public <R extends SyntaxNode, O extends Node> java.util.List<O>
$$(java.util.Collection<? extends SyntaxNode<R extends SyntaxNode>> input,
java.lang.Class<O> outputType) { return (List<O>)null;} {code}
which of course doesn't compile, because {{extends SyntaxNode}} does not belong
to the type declaration of the method parameter.
The issue seems to only affect parameters whose types are themselves
constrained, note that the other method parameter works just fine.
