what is the kotlin equivalent of

Map<Class, Object>

? intellij suggests both

Map<Class<Any>, Any>

and

Map<Class<*>, Any>

as parameter type, but neither work when calling the method from java

Yes,

Class

is a legacy raw type and should not be used in Java. Kotlin does not support them.

See https://youtrack.jetbrains.com/issue/KT-30363#focus=streamItem-27-3344960.0-0 for examples of

Map

interop with Java and a little explanation.
