JBM 1.2.x depends on common-core common-logging-log4j common-logging-spi but JBAS 4.2 depends on jboss/common. My assumption is we depend on the core, logging etc so as not to have to drag in the entire jboss common jar. My question is though, how do I know what version of common-core, common-logging etc is compatible with what version of jboss common? We are currently using common-core 2.2. JBAS 4.2 will be using jboss common 1.2.GA. How do I know if these are compatible, so we can deploy unscoped?
