WRT - https://jira.jboss.org/jira/browse/JBAS-6600 current impl of EarClassLoaderDeployer looks pretty much broken. | public void deploy(DeploymentUnit unit, JBossAppMetaData metaData) throws DeploymentException | { | ClassLoadingMetaData classLoadingMetaData = unit.getAttachment(ClassLoadingMetaData.class); | if (classLoadingMetaData != null) | return; | | LoaderRepositoryMetaData lrmd = metaData.getLoaderRepository(); | if (lrmd != null) | { | ClassLoadingMetaData clmd = LoaderRepositoryMetaDataHelper.create(unit, lrmd); | // For isolated automatically create the classloader in a new domain | if (clmd == null && isolated) | { | String domain = EARDeployment.getJMXName(metaData, unit) + ",extension=LoaderRepository"; | classLoadingMetaData = new ClassLoadingMetaData(); | classLoadingMetaData.setName(unit.getName()); | classLoadingMetaData.setDomain(domain); | classLoadingMetaData.setExportAll(ExportAll.NON_EMPTY); | classLoadingMetaData.setImportAll(true); | classLoadingMetaData.setVersion(Version.DEFAULT_VERSION); | classLoadingMetaData.setJ2seClassLoadingCompliance(false); | } | } | } | 1) Why only do isolation if LRMD is present? (as Jaikiran noted) 2) Even if isolation kicks in, it's never attached 3) LoaderRepositoryMetaDataHelper and LoaderRepositoryConfigHelper have duplicated code View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4217356#...
