checking a "self-defined" permission (extends java.security.Permission) does not work

I have problems in using Permission derived from java.security.Permission
with the felix ConditionalPermissionAdmin.

I have 3 bundles:

• PermissionManagement: defines MyPermission class and assigns this permission to all bundles
• Provider: exposes a function f with security check on MyPermission
• Consumer: try to use function f

I run these bundles in felix + framework.security + scr and got access denied
(Consumer is not allowed to use function f although MyPermission is already assigned to all bundles)

Problems in detail:

I have a bundle named PermissionManagement which defines a new Permission class
as follows:

public class MyPermission extends Permission {
private String actions;

public MyPermission(String name, String actions)

{ super(name); this.actions = actions; System.out.println("MyPermission constructor called with params: " + name + ", " + actions); }

...

@Override
public String getActions()

{ System.out.println("MyPermission getActions method called"); return this.actions; }

}

PermissionManagement also defines a class called "PermissionManager" to assign
MyPermission to all bundles using ConditionalPermissionAdmin as follows:

cpa.addConditionalPermissionInfo(new ConditionInfo[]

{ null }

,
new PermissionInfo[]

{ new PermissionInfo( MyPermission.class.getName(), "MyName", "MyAction") }

);

Provider bundle defines a class DummyProvider which exposes a function F guarded with security check

public String f() {
MyPermission myPerm = new MyPermission("MyName", "MyAction");
SecurityManager security = System.getSecurityManager();
if (security != null)

{ security.checkPermission(myPerm); }

return "test";
}

Consumer bundle has an Activator as follows:
public class Activator implements BundleActivator {

@Override
public void start(BundleContext arg0) throws Exception

{ DummyProvider dp = new DummyProvider(); System.out.println(dp.f()); }

...
}

in felix shell
-> start file:///.../consumer-1.0-SNAPSHOT.jar
DummyProvider constructor called
MyPermission constructor called with params: MyName, MyAction
MyPermission hashCode method called
MyPermission hashCode method called
MyPermission hashCode method called
MyPermission hashCode method called
MyPermission getActions method called

java.security.AccessControlException: access denied (testbundles.permissionmanagement.MyPermission MyName MyAction)
