This patch allows you to disable the flash cross domain handler by adding “flashcrossdomain.enabled” in the jiveProperty table.
I filed as OF-71
A similar solution has been implemented as part of OF-21. The property that has been used is slightly different from the one suggested in your patch though. The property that will allow you to control the module is flash.crossdomain.enabled
Thanks for the follow-up Guus. Apparently I need to learn how to better search jira
