Confluence relies on a number of Java libraries. Some of these libraries make use of features of the Java language that may be restricted by Java security policies.

This does not normally cause any problems. The default security configuration of most application servers will happily run Confluence. However, in some shared-hosting or enterprise environments, security settings may be such that Confluence cannot function.

When you attempt to run Confluence, you may get the following error:

java.security.AccessControlException: access denied (java.lang.RuntimePermission accessDeclaredMembers)
        at java.security.AccessControlContext.checkPermission(AccessControlContext.java(Compiled Code))
        at java.security.AccessController.checkPermission(AccessController.java(Compiled Code))
        at java.lang.SecurityManager.checkPermission(SecurityManager.java(Compiled Code))

The permissions required by Confluence to run are detailed in the sample policy file below. You may need to give this information to your systems administrator so that they can be deployed with the Confluence application.

grant codeBase "file:${catalina.home}/webapps/confluence/-" {
permission java.security.AllPermission;
};

grant {
permission java.lang.RuntimePermission "accessDeclaredMembers";
permission java.lang.reflect.ReflectPermission "suppressAccessChecks";
permission java.lang.RuntimePermission "defineCGLIBClassInJavaPackage";
};
