Why JBoss EAP 6/7 is unable to load some of the JDK provided classes

Issue

• We have observed that EAP 6/EAP 7 is unable to load some of the JDK provided classes.

• I have a static module used that requires classes found in JAR files that are included in the BOOTCLASSPATH but not in the rt.jar file. How can I make the module see them?

• We are getting the following exception when an application deployed on JBoss EAP6 tries to load the sun.net.www.protocol.http.HttpURLConnection class:

ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/SimpleBindDemo].[jsp]] (http-localhost/127.0.0.1:8080-1) Servlet.service() for servlet jsp threw exception: java.lang.ClassNotFoundException: sun.net.www.protocol.http.HttpURLConnection from [Module "deployment.SimpleBindDemo.war:main" from Service Module Loader]

• Deployment failure while loading rt.jar
• On deploying application war on the Jboss 6.3.2 EAP we are getting error message in server logs. It seems like Jboss is not able to load classes from rt.jar which is a Java library.
• We have configured the modules in Jboss configuration as required, the module.xml file in {JBOSS_HOME}\modules\system\layers\base\sun\jdk\main folder has been updated with the entries for com.sun.jndi.toolkit.url package.
