Hi

http://validator.w3.org/nu/ flags TH ABBR as obsolete but it's not listed as obsolete in HTML 5.0 Rec, 5.1 draft or WhatWG specs.

http://www.w3.org/TR/html5/tabular-data.html#the-th-element
https://html.spec.whatwg.org/multipage/tables.html#attr-th-abbr

(Seem to recall it being listed as obsolete in an HTML5 spec a couple of years back)

<!DOCTYPE html>
<title>tests</title>
<body>
	<table>
	<tr>
		<th>Criteria</th> <th abbr="Features">Supporting Features</th> 
		<th abbr="Remarks">Remarks and explanations</th>
	</tr>
	</table>
</body>				


This looks like the cause in Assertions.java:
OBSOLETE_ATTRIBUTES.put("abbr", new String[] { "td", "th" });

Seems like it's supported in at least one screen reader:
