Groovy 3 throws error when accessing fields

[aibolit]

I am getting the following exception in Groovy3 but not Groovy2

Exception in thread "main" java.lang.NoSuchFieldError: field

Here's a screenshot of the debugger

To reproduce I created a minimalist project: https://github.com/aibolit/StandaloneGORM-Groovy3/tree/groovy3derby (branch groovy3derby).

To reproduce just ./gradlew run

If you change build.gradle to use Groovy 2.5.12, the code will work.

GORM for Hibernate version 7.0.4 does not support Groovy 3, please try with GOMR 7.1.0.M2 which supports Groovy 3.
