jbossts-common.jar includes commons-logging Log4JLogger ------------------------------------------------------- Key: JBTM-200 URL: https://jira.jboss.org/jira/browse/JBTM-200 Project: JBoss Transaction Manager Issue Type: Bug Security Level: Public(Everyone can see) Reporter: Scott M Stark Assignee: Jonathan Halliday Fix For: 4.2.3 The jbossts-common.jar jar includes an implementation of the commons-logging Log interface: [starksm@succubus lib]$ jar -tf jbossts-common.jar | grep Log4 org/apache/commons/logging/impl/Log4JLogger.class This cannot be included in jars bundled in jbossas as it conflicts with the commons logging classes we bundle with the server. Either this needs to be extracted to a jar that is not included, or simply an external dependency that requires a valid commons logging jar.
