Here's a first cut at replacing jQuery 1.2.3 with 1.4.3. I looked for all the places where 1.2.3 was mentioned and upgraded (including licence statements), removed 1.2.3 and added 1.4.3 to webapp/web/admin.
I've done very cursory testing so far, debug.jsp comes up, I can look at the schema and the solr/browse page "looks ok".
No test are failing as a result of this patch.
Where should I test next?
