dennis lucero updated NETBEANS-3791:
------------------------------------
Description:
In an annotation processor similar to
{code:java}
@SupportedAnnotationTypes("org.example.MyAnnotation")
public final class MyGenerator
extends javax.annotation.processing.AbstractProcessor {
@Override
public boolean process(
final Set<? extends TypeElement> annotations,
final RoundEnvironment roundEnvironment) {
final Set<? extends Element> elements
= roundEnvironment.getElementsAnnotatedWith(MyAnnotation.class);
for (final Element element : elements) {
PackageElement packageElement = null;
for (Element currentElement = typeElement;
currentElement != null;
currentElement = currentElement.getEnclosingElement()) {
if (currentElement instanceof PackageElement) { // Illegal Use
of instanceOf
packageElement = (PackageElement) currentElement;
break;
}
{code}
I get the warning “Illegal Use of instanceOf operator” (in the line with the
comment). It is unclear why this use would be illegal, as it works fine.
The description of the hint in the options should clearly say why it’s illegal
to use instanceOf or, if this warning is obsolete, the hint should be removed.
(According to http://wiki.netbeans.org/Java_Hints, this hint is disabled by
default.)
