commons-logging is a dependency of Tomcat 5.5, however it is included in the default config via the ws4ee sar. Since it is a dependency of both, shouldn't it be removed from ws4ee and added to default lib? So that we go from:

./lib/commons-logging.jar
./server/all/lib/commons-logging.jar
./server/all/deploy/jboss-ws4ee.sar/commons-logging.jar
./server/default/deploy/jboss-ws4ee.sar/commons-logging.jar

to:

./lib/commons-logging.jar
./server/all/lib/commons-logging.jar
./server/default/lib/commons-logging.jar
