        This issue was to add the option over a year ago; if the option needs to be removed, please open a new ticket.

        That said, I couldn't find anything in the change log for removing UseCondCardMark.

        I'm getting an error that the UseCondCardMark option is invalid on JDK 7u40.

        I reverted this accidentally during a merge from 1.1 (02308f6f9ae272fde101357a7d395f0118b80d0d). So it didn't actually make it into beta1 after all.

        Re-committed in 1423fb11037ef23aef3e78516d8d2e8f7acb54ba.
