Mocking fails in a test method containing space in its name

[MastaP]

Another bug has emerged while working on #441
The following two methods have identical bodies, the only difference is in test methods' names, the second one contains a space

    @Test
    fun test() {
        val deferredSupplier = spy(java.util.function.Supplier { Flux.empty<String>() })
        Flux.defer(deferredSupplier).blockLast()
        verify(deferredSupplier, times(1)).get()
    }

    @Test
    fun `test spy`() {
        val deferredSupplier = spy(java.util.function.Supplier { Flux.empty<String>() })
        Flux.defer(deferredSupplier).blockLast()
        verify(deferredSupplier, times(1)).get()
    }

The error message is:

Mockito cannot mock this class: class com.example.Test$test spy$deferredSupplier$1.
Can not mock final classes with the following settings :
 - explicit serialization (e.g. withSettings().serializable())
 - extra interfaces (e.g. withSettings().extraInterfaces(...))

You are seeing this disclaimer because Mockito is configured to create inlined mocks.
