[jboss-as7-dev] Question about Async logging

[Ales Justin]

Looking at the code, I would say that's a bug.

        final EnumSet<Attribute> required = EnumSet.of(Attribute.FILE_NAME, Attribute.NAME);
        final int count = reader.getAttributeCount();
        for (int i = 0; i < count; i++) {
            requireNoNamespaceAttribute(reader, i);
            final String value = reader.getAttributeValue(i);
            final Attribute attribute = Attribute.forName(reader.getAttributeLocalName(i));
            required.remove(attribute);
            switch (attribute) {
                case NAME: {
                    name = value;
                    break;
                }
                default:
                    throw unexpectedAttribute(reader, i);
            }
        }
        if (!required.isEmpty()) {
            throw missingRequired(reader, required);
        }

Since as you can see, FILE_NAME' value (if present) is never actually used / handled.
