12/04/2019, 3:43 PMASFAIU this is a bug:
Copy code
interface A {
}
class B<T extends @NotNull A> {
}Ivan Kubyshkin [JetBrains]
12/04/2019, 3:44 PMThis code should be converted to not nullable type
Ivan Kubyshkin [JetBrains]
12/04/2019, 3:44 PMBut it doesn't
p
Pacane
12/04/2019, 3:44 PMyeah I tried it as well
