Scott Murphy Heiberg created GROOVY-12618:
---------------------------------------------
Summary: A public static super trait method called from a closure
in trait code ignores the closure's delegate
Key: GROOVY-12618
URL: https://issues.apache.org/jira/browse/GROOVY-12618
Project: Groovy
Issue Type: Bug
Affects Versions: 5.0.8, 6.0.0
Reporter: Scott Murphy Heiberg
{code:groovy}
trait T { static int size() { 1 } }
trait U extends T {
def m() { [5, 6].with { size() } }
static sm() { [5, 6].with { size() } }
}
class C implements U {}
assert new C().m() == 2
assert C.sm() == 2
{code}
Actual: both calls return 1, in dynamic, @TypeChecked and @CompileStatic code.
Expected: 2, as with the same code written with classes. Inside a with closure,
the list delegate's size() comes before the owner's.
The trait transformation rewrites an implicit-this call to a public static
method inherited from a super trait into a direct call on the trait helper
class, so the closure's delegate is never consulted. GROOVY-12611 changes this
for private and static methods declared by the trait itself, but not for
methods inherited from a super trait.
Seen in 5.0.8 and 6.0.0.
