Unrechable code o.j.j.c.annotations.Annotations

The condition

values.size() == 0

in o.j.j.c.annotations.Annotations#L259
https://github.com/ironjacamar/ironjacamar/blob/1.5.2.Final/common/impl/src/main/java/org/jboss/jca/common/annotations/Annotations.java#L259 is not reachable because

Collection<Annotation> values = annotationRepository.getAnnotation(javax.resource.spi.Connector.class);

will contain null instead of a empty Collection https://github.com/ironjacamar/ironjacamar/blob/1.5.2.Final/common/impl/src/main/java/org/jboss/jca/common/annotations/Annotations.java#L245

In line 246 is

if (values != null)
}

which prevents any later check. In the else of L246 must be the error handling of L261-L266
