Subject: [PATCH] Fix InternalAttribute.equals

Motivation:

InternalAttribute doesn't extend Attribute, but its equals only returns true when it compares with an Attribute. So it will return false when comparing with itself.

Modifications:

Make sure InternalAttribute return false for non InternalAttribute objects.

Result:

InternalAttribute's equals works correctly.
