Can't instantiate proxy for class kotlin.Function2 - similar class definition #997

I am receiving the same This started happening after bumping to version For our use case, we are simply mocking a kotlin interface for a test. private var testDetails: Details? = null
private val billingInventory: IBillingInventory = mockk {
every { getDetails() } answers { testDetails }
}which causes Other instances involve mockking a java class that's provided via Dagger/Hilt which causes the same exception above. The main source I can find that could have possibly caused this was this recent change added in Can anyone shed some light on why the exception is thrown? |

We are seeing something similar. We upgraded from 1.12.2 to 1.13.4. We started seeing flakiness in tests due to the WeakReference. It's likely that there is a GC before the reference is attached to anything. package com.test
import io.mockk.proxy.common.CancelableResult
import org.junit.jupiter.api.Test
class MockkTest {
data class Payload(val something: String)
@Test
fun testing() {
val result = CancelableResult(Payload("hello world"))
System.gc()
print(result.get())
}
}Result: |

Created a PR with a fix for handling GCs but removing the WeakReference from ProxyMaker: #1052 |
Issue #997 - Simulate garbage collected proxy
|
Hello I came here looking for some answers related to the I noticed that the PR was merged two days ago. Do we have visibility of when the new release will come? Thank you in advance |

Just released 1.13.5! |
|
I still get |

This seems to have undid the fix from #1013, now I still have memory leaks since GC can't collect the spy objects when they're cleared. |

We also have increased flakyness in our tests after updating to JDK17 and Mockk Android 1.13.4. We got the following issues very frequently: Would like to add, that the only other change we have done is using the JVM parallel garbage collector as mentioned in an Android Documentation: We also disabled that for now. Can this be related? |
May I ask if this ... issue fixed in |
|
@JooHyukKim Yes this is fixed in 1.13.5 |

@ygaller Thank you for letting me know! 👍🏼 |
JDK 19
Quarkus 2.14.3.Final
Mockk 1.13.3
JUnit 5.9.1
I'm trying to replace an existing instance with mock:
typealias BroadcastSwitchActiveComputer = suspend (Computer) -> Either<BroadcastSwitchActiveComputerError, Unit>kotlin.jvm.functions.Function2<? super Computer, ? super kotlin.coroutines.Continuation<? super arrow.core.Either<? extends BroadcastSwitchActiveComputerError, ? extends kotlin.Unit>>, ?>I have several beans with similar Function2 class definition. However they have different Either's generic type.
