Flash player acquires crossdomain.xml via https while the swf is loaded via http

Hi folks,

I updated FP to 19 version and now if I run my flex project compiled in release I see the https://localhost:8080/crossdomain.xml request. While the application is loaded from http://localhost:8080/launcher.swf.

Of course request can't be satisfied and app crushes. In debug there is no request.

Before update it worked perfectly, thanx in advance.
