Problem with Bean Mapping Style due to Type Erasure #457
When using Bean MappingStyle (using @id on getters), an issue is being encountered with the use of the @id annotation on an extended generic method. This results in an ENTITY_WITHOUT_ID Exception ("Class '%s' mapped as Entity has no Id property. Use @id annotation to mark unique and not-null Entity identifier") being thrown.
This can be easily replicated when we have an abstract Parent class that defines a getter method which is overridden by a child class getter annotated with @id. Example:
Due to type erasure and generated bridge method (https://docs.oracle.com/javase/tutorial/java/generics/bridgeMethods.html), the following methods will be generated:
In JaversMethodFactory.getAllMethods(), sometimes this method processes the 'bridge' method first, before our method, and this results in our method to be skipped since the logic filters inheritance duplicates. A suggested solution is to skip the bridge method, thus our method can be added.
PR with failing test case and proposed solution will be pushed soon.
