I do not know if this is the right place to report, because it is not a bug. We are using JBoss 3.2.5 on Gentoo for almost 4 months on two productionssystems without any jboss related problems. The servers are serving several domains. The main domains are http://publications.uu.se and http://www.diva-portal.org. There are about 30 different applications installed and the system are running well. I would suggest to move the 3.2.5 release to stable.
marked 3.2.5 stable, there are issues with jboss like packed jars etc but that's a generall issue. hopefully, we'll be able to provide an ebuild for 4.0.x which doesn't relies up on packed jars in the near future. we're on it. thanks for your report.
