[jira] [Created] (GROOVY-10583) Stub generator handles method type parameter bounds incorrectly

Krzysztof Sierszeń created GROOVY-10583:
-------------------------------------------

             Summary: Stub generator handles method type parameter bounds incorrectly
                 Key: GROOVY-10583
                 URL: https://issues.apache.org/jira/browse/GROOVY-10583
             Project: Groovy
          Issue Type: Bug
            Reporter: Krzysztof Sierszeń


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.
