regression in 20.0 on LambdaFetchingSupport , Kotlin data class, Spring boot #3121
Description
I am trying to upgrade the library from 18.0 to 20.0 today and found below regression.
Describe the bug
The LadmbdaFetchingSupport has a regression that causeS this error:
java.lang.ClassCastException: part.to.namespace.Xxx incompatible with part.to.namespace.Xxx
at graphql.schema.PropertyFetchingImpl.getPropertyValue(PropertyFetchingImpl.java:76) ~[graphql-java-20.0.jar:na]
at graphql.schema.PropertyDataFetcherHelper.getPropertyValue(PropertyDataFetcherHelper.java:22) ~[graphql-java-20.0.jar:na]
at graphql.schema.PropertyDataFetcher.getImpl(PropertyDataFetcher.java:131) ~[graphql-java-20.0.jar:na]
To Reproduce
Environment: Java 17, Kotlin 1.8.0,
last known good library version: 19.3
// This works
object.getClass().getDeclaredMethods()[0].invoke(object)
// This doesn't work
LambdaFetchingSupport.createGetter(object.getClass(), "id").get().apply(object)I wasn't able to re-produce the error with the exact same class in Junit environement.
Two different things maybe related when I check the object.getClass()
In Junit, the class loader is ClassLoaders$AppClassLoader
In application , it is RestartClassLoader from Spring.
