io.mockk.MockKException: 
Class cast exception happened.
WARN: 'message' property in ClassCastException provided by JVM is null, autohinting is not possible. 
This is most probably happening due to Java optimization enabled. 
You can use `hint` before call or use -XX:-OmitStackTraceInFastThrow to disable this optimization behaviour and make autohiniting work. 
For example in gradle use: 

test {
   jvmArgs '-XX:-OmitStackTraceInFastThrow'
}
Is there a similar option for use with maven?
