Paul King resolved GROOVY-9769.
-------------------------------
Fix Version/s: 4.0.0-alpha-2
3.0.7
Resolution: Fixed
Merged, thanks. I don't believe there is anywhere where we are relying on the
redundant interfaces. Hopefully no downstream projects do.
> STC: UnionTypeClassNode created for simple instanceof scenarios
> ---------------------------------------------------------------
>
> Key: GROOVY-9769
> URL: https://issues.apache.org/jira/browse/GROOVY-9769
> Project: Groovy
> Issue Type: Bug
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Minor
> Fix For: 3.0.7, 4.0.0-alpha-2
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> Consider the following:
> {code:groovy}
> interface A {
> def foo() {}
> }
> interface B extends A {
> def bar() {}
> }
> @groovy.transform.CompileStatic
> void test(A a) {
> if (a instanceof B) {
> a.foo()
> a.bar()
> }
> }
> {code}
> Variable expression "a" infers to "<UnionType:A+B>" due to {{instanceof}}
> screening. Since B extends A, a simple ClassNode for B should be sufficient.
> The union types are harder to deal with for consumers. This is a variant of
> GROOVY-7333.
