Eric Milles commented on GROOVY-11685:
--------------------------------------
This fails under STC because postProcessClosure accepts "unknown type that
extends ResultBase". It should be declared as "Consumer<ResultBase>" or
"Consumer<? super ResultBase>". I linked the issue detailing the wildcard
capture changes.
{code:groovy}
Consumer<? extends ResultBase> postProcessClosure
ResultBase analyzed = closure.apply(str)
postProcessClosure(analyzed)
{code}
> Static type checking fails with groovy 5.x
