Its more than just the logging that is taking the time. If I reduce the logging to INFO level, parsing a standardjboss.xml descriptor is still taking > 60 seconds: 11:33:28,038 INFO [JBoss50UnitTestCase] EjbJar21Everything_testEverything.xml parse time = 1227 11:34:34,711 INFO [JBoss50UnitTestCase] JBoss5xEverything_testStandard.xml parse time = 66673 11:34:44,040 INFO [JBoss50UnitTestCase] JBoss5xEverything_testEverything.xml parse time = 9329 Seems like we need to cache the fact that a given element is a unknown wildcard to avoid the resolution thrashing going on.
