Duplicated transactionManager property in Grails service


When implementing a specialized Grails service (inherited from another concrete service class) I'm ending up with a weird duplicated transactionManager property. Here is what I get when inspecting the specialized service class:

<a href="https://i.stack.imgur.com/OYlQf.png" rel="nofollow"><img alt="enter image description here" class="b-lazy" data-src="https://i.stack.imgur.com/OYlQf.png" data-original="https://i.stack.imgur.com/OYlQf.png" src="https://etrip.eimg.top/images/2019/05/07/timg.gif" /></a>

Both service classes are annotated as @Transactional:

@Transactional(readOnly = true) class FormularioService { } @Transactional(readOnly = true) class FormularioCurriculoService extends FormularioService { }

This behavior leads to NullPointerException's during transaction AOP.

1) How can an instance has two properties with the same name?

2) What could I do to keep services with a single transactionManager property (non-specialized service classes just don't present this kind of bug)


Just NEVER annotate an specialized service class with @Transactional, if the super class is already annotated.

@Transactional(readOnly = true) class FormularioService { } //Don't annotate with @Transactional class FormularioCurriculoService extends FormularioService { }
