ParamQuery was originally a Java class with default constructor with getter/setters. I converted it to a Kotlin data class with constructor params only and it broke the original behavior. Making the params properties of the data class restored the original behavior but that loses the niceness of a data class (equals/hash/copy). It should work the same so it seems like a bug?
