Subject [jira] [Commented] (UIMA-6054) JCasGen generating warnings by creating deprecated constructors
Date Thu, 06 Jun 2019 17:08:00 GMT

    [ https://issues.apache.org/jira/browse/UIMA-6054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16857899#comment-16857899

Hai-Son Nguyen commented on UIMA-6054:
--------------------------------------

Yes, I can see where a subtype class may have problems if this default constructor is missing.
In my use case, we have base classes that extend off of Annotation and see this warning only
on immediate subclasses of Annotation.

This patch is extracting the superclass for the class being generated and using it to determine
the need for the SupressWarning ("Annotation".equals(supertype))

I also looked at the Component Descriptor Editor UI and it requires a SuperType and not sure
if one can produce a class not originally extended from uima.tcas.Annotation. If this is the
case, the deprecated constructor is inherited and available for all subclasses and defining
it in each class is redundant.

> The JCasGen process produces classes with a protected empty no parameter constructor.
> Base classes that have extended the Annotation class (org.apache.uima.jcas.tcas.Annotation)
are now getting warnings that the constructor Annotation() is deprecated.
> The constructor documentation states, "Never called. Disable default constructor" but
the presence of other constructors already serve this purpose.
