[jira] [Updated] (UIMA-5067) JCasUtil.selectSingleRelative returns wrong object

["Richard Eckart de Castilho (JIRA)" <de...@uima.apache.org>]

     [ https://issues.apache.org/jira/browse/UIMA-5067?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Richard Eckart de Castilho updated UIMA-5067:
---------------------------------------------
    Description: 
The returned object of JCasUtil.selectSingleRelative() should match the generic-type of its first argument.
However, when the last argument is 0, it returns an object whose class is identical to the second argument's class.

{noformat}
for (Annotation aa : cas.getAnnotationIndex(AA.type))
{
   Object ab = JCasUtil.selectSingleRelative(AB.class, aa, 0);
   System.out.println(ab.getClass().getName());
}
{noformat}

The output ought to be "AB", however it is "AA".

(When the last argument is 0, I thought it would find an annotation which begins exactly where the annotation of the second argument begins. However, it returns a wrong object).

Perhaps, if last-argument 0 is prohibited, an exception should be thrown (and documented).

Thanks.
