remove felix.security after framework is started?

[Andrei Pozolotin]

    Hello,

    can you please let me what is the clean way to remove felix.security
    fragment bundle
    after the framework is already started with it?

    if I just call bundle.uninstall() on this fragment, the framework
    does remove it
    but becomes unusable, blows up with class not found exceptions;

    Thank you,

    Andrei
