ASTVisitor and SimpleType.resolveBinding(): wrong ITypeBinding [message #662625]

Hi all,

I have a little problem with resolving some bindings for SimpleTypes.

Take this example:

import org.eclipse.uml2.uml.Package;

public abstract class JavaLangImports
{
public abstract Package m1();
public abstract java.lang.Package m2 ();
}

When I look at it with the Java Editor, the Package for m1() is correctly
resolved as org.eclipse.uml2.uml.Package (maybe it is worth mentioning here
that this is also the case when opening the source file externally without
having it in a source path anywhere. So I guess that the compiler has no
hand in this).

When I visit the file with my own ASTVisitor however, I get a TypeBinding
for java.lang.Package for both methods.

The AST visitor is created like this:

IJavaElement javaElement = JavaCore.create(file);
ICompilationUnit compilationUnit = (ICompilationUnit)javaElement;
ASTParser parser = ASTParser.newParser(AST.JLS3);
parser.setKind(ASTParser.K_COMPILATION_UNIT);
parser.setSource(unit);
parser.setResolveBindings(true);
CompilationUnit parsedUnit =
(CompilationUnit)parser.createAST(monitor);
MyVisitor visitor = new MyVisitor(visitProgress);
parsedUnit.accept(visitor);

and in MyVisitor

public boolean visit(SimpleType node)
{
ITypeBinding b = node.resolveBinding();
//is java.lang.Package in both cases
System.out.println(b.getQualifiedName());
return false;
}

Is there some magic I need to perform to make the AST resolve the correct
types? Or is this a bug?

Best regards,
Carsten Reckord

Hi,

Please open a bug report against JDT/Core with steps to reproduce, build id and anything that might help us to fix it.
I'll take a look.

Thanks,

Olivier

Argh, dangit. I found my problem. Why is it that it always hits you after
hitting submit...

The sample code I posted was not in my workspace, but part of a unit test
suite where it gets imported into a test workspace. So without the compiler
complaining to me, I didn't see that there was no org.eclipse.uml2 in the
classpath...

Everything works as intended now.

Thanks,
Carsten
