(Consumer) IllegalAccessException when using some unexpected types as state parameters

[gaeljw]

When changing the state parameters of one contract from a Int to a Seq[Int], I've got the following exception on the consumer:

[info]   kotlin.reflect.full.IllegalCallableAccessException: java.lang.IllegalAccessException: class kotlin.reflect.jvm.internal.calls.CallerImpl$FieldGetter cannot access a member of class scala.collection.immutable.$colon$colon with modifiers "private final"

Relevant code:

ConsumerPactBuilder
    ....
   .`given`("Some entities", Map("ids" -> Seq(123, 456)))

Sounds related to using Scala types that Pact JVM itself is not able to convert to a known Java type. Not necessarily a big issue, I just log it in case anyone face it as well.

[gaeljw]

Transforming the objects to Java (with standard Scala converters) works fine.

yeah the state stuff was always a little janky/unsafe - I'll see what we can do to make it more usuable ootb

[jbwheatley]

think I fixed this on main, not release yet

[jbwheatley]

fixed in 0.12.1, please reopen if not the case
