JBoss Module does not add package "org.jcp.xml.dsig.internal" as system package ------------------------------------------------------------------------------- Key: WFLY-4317 URL: https://issues.jboss.org/browse/WFLY-4317 Project: WildFly Issue Type: Enhancement Components: Class Loading Affects Versions: 8.2.0.Final Reporter: xiaodong xie Assignee: David Lloyd The package "org.jcp.xml.dsig.internal" was included in both JDK 7 and JDK 8, but it is not added as a system package in jboss-module. So, if we do this: String providerName = System.getProperty("jsr105Provider", "org.jcp.xml.dsig.internal.dom.XMLDSigRI"); XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM", (Provider) Class.forName(providerName).newInstance()); We cannot find this "org.jcp.xml.dsig.internal.dom.XMLDSigRI" at runtime. The current workaround is to hack "standalone.conf" file, added "org.jcp.xml.dsig.internal" package after package "org.jboss.byteman". if [ "x$JBOSS_MODULES_SYSTEM_PKGS" = "x" ]; then JBOSS_MODULES_SYSTEM_PKGS="org.jboss.byteman,org.jcp.xml.dsig.internal" fi
