Mockito cannot mock/spy because : VM does not support modification of given type #441
Description
Hi,
After switching kotlin's api/language from 1.4 to 1.5, the following code:
@Test
fun test() {
val deferredSupplier = spy(Supplier { Flux.empty<String>() })
Flux.defer(deferredSupplier).blockLast()
verify(deferredSupplier, times(1)).get()
}
fails with
Cannot mock/spy class com.example.Test$$Lambda$318/0x00000008001dc840
Mockito cannot mock/spy because :
- VM does not support modification of given type
I'm using org.mockito.kotlin:mockito-kotlin:3.2.0 and org.mockito:mockito-inline:3.12.4
The issue is reproduced in the following project, where the only difference between two commits is changing Kotlin's api from 1.4 to 1.5
