I'm trying to get an ITypeBinding for a parameterized type. When I pass in 
java.util.List<Integer> to the following method, I get an npe in the jdt code. 
See below for stack trace:

  public static ITypeBinding getTypeBinding(final String typeName, 
IJavaProject javaProject)
    {
        class BindingRequestor extends ASTRequestor
        {
            private ITypeBinding _result = null;
 
            public void acceptBinding(String bindingKey, IBinding binding)
            {
                if (_result == null && binding != null && binding.getKind() == 
IBinding.TYPE)
                _result = (ITypeBinding) binding;
            }
        }

        String[] keys = new String[] { BindingKey.createTypeBindingKey( 
typeName ) };
        final BindingRequestor requestor = new BindingRequestor();
        final ASTParser parser = ASTParser.newParser(AST.JLS3);
        parser.setResolveBindings(true);
        parser.setProject(javaProject);
        // this doesn’t really do a parse; it’s a type lookup
        parser.createASTs(new ICompilationUnit[] {}, keys, requestor, null);
        return requestor._result;
    }
