In thread "[JENKINS] Lucene-Solr-SmokeRelease-4.x - Build # 69 - Failure" miller suggested that we should phase out the concept of a default core name by 5.x – removing this is probably easy, but we need to change a lot of little things to do this cleanly.
Off the top of my head...
- smoke checker assumes simple URLs
- post.jar - needs to make URL mandatory
- lots of doc examples need updated
