Hi guys. I trying to mock a method that returns coroutine Job
But I get this runtime exception

java.lang.IllegalArgumentException: proxied interface methods have incompatible >return types:

public abstract boolean kotlinx.coroutines.Job.cancel()

public abstract void kotlinx.coroutines.Job.cancel()

at java.lang.reflect.Proxy.validateReturnTypes(Proxy.java:328)
