Steps to Reproduce

In grails 3.3 currently impossible to define enumType for a collection of enums. It works only for a separate field:

With grails 3.2 following code works well, but with grails 3.3 it use enum names during saving to DB

class Test {
   Set<TestEnum> enums
   static mapping {
     enums  enumType: 'identity' // not works 
   }
}

enum TestEnum {
   final int id
   TestEnum(int value){
   ...
   }
}
