---------------------------------------

             Summary: WebConsole doesn't start with Java Secruity enabled
                 Key: FELIX-4610
                 URL: https://issues.apache.org/jira/browse/FELIX-4610
             Project: Felix
          Issue Type: Bug
          Components: Web Console
    Affects Versions: webconsole-4.2.2
            Reporter: Valentin Valchev
            Assignee: Valentin Valchev
            Priority: Blocker
             Fix For: webconsole-4.2.4


The framework is run with java security enabled. When I attempt to start the webconsole there is an exception:
{code}
java.security.AccessControlException: access denied ("org.osgi.framework.ServicePermission" "(service.id=44)" "get")
        at java.security.AccessControlContext.checkPermission(AccessControlContext.java:366)

        at org.apache.felix.webconsole.internal.servlet.OsgiManager.updateConfiguration(OsgiManager.java:1002)
        at org.apache.felix.webconsole.internal.servlet.ConfigurationSupport.updated(ConfigurationSupport.java:51)
{code}

The reason for this exception is that Web Console tries to access a service in it's updated method. Since configuration admin bundle doesn't have enough permission the call fails and the /system/console alias doesn't get registered.

To solve that issue, the updated method should use doPrivileged when performing the operations. 

The same applies to the "service* method of the HttpServlet. According the OSGi R5 compendium specification chapter 102.8.3, "it is the responsibility of the Servlet and Http Context implementations to use a doPrivileged block when performing privileged operations."
