Class reference is failed when include 'or' at a package name

[kazuki43zoo]

If package name includes "or" (e.g. "jp.or.example"), the Ognl#parseExpression(String) is failed as follow:

• Code

    public void test_class_reference()
        throws Throwable
    {
        OgnlContext context = (OgnlContext) Ognl.createDefaultContext(null, new DefaultMemberAccess(false));
        {
            Node expr = (Node) Ognl.parseExpression("@java.util.UUID@randomUUID()"); // It's OK
            Object v = expr.getValue(context, null);
            System.out.println(v);
        }
        {
            Node expr = (Node) Ognl.parseExpression("@jp.or.example.IdUtils@generateId()"); // It's failed on parsing phase
            Object v = expr.getValue(context, null);
            System.out.println(v);
        }
    }
