Cannot retreive annotation member value from ClsAnnotationImpl

Hi,

I'm currently developping an IntelliJ plugin to support a 3rd party Java framework.

I need to retreive some annotation members value. Everything works fine when working on class files located in an opened module, but I always receive 'null' when the file is located in a jar file.

Is it normal ? Or is there another way to retreive this value ?

Thanks, best regards,

Gauthier
