A DESCRIPTION OF THE PROBLEM :
When generated type is used as class for generic record property, compilation fails with the following stacktrace:

This issue is similar to https://bugs.openjdk.org/browse/JDK-8273408, but this time generated class is used not as record property type, but as type parameter for generic record property value.
