: That is a convincing argument, admittedly. But by using SLF4J, Solr won't : alienate users using such containers (like me, using JBoss 3.x), ANY : container should be fine based on the way SLF4J works.
Unless that container already uses SLF4J (ahem: jetty) and the version used by the container is differnet then the version used by the war ... in which case class version incompatibilities could arrise. With JUL, there is never any possiblity of a problem like this. -Hoss
