Javafx use jmf and capture audio device

[joe mock]

Hello, I noticed a problem with the use JavaFX and Java Media Framework (JMF), in a project javafx call Java classes using JMF, but are not recognized PC audio devices, in fact when I executed 's the code CaptureDeviceManager.getDeviceList (null) displays the error "could not commit protocolPRefixList", without recognizing any audio device. Instead I call if my application using JMF, outside of a JavaFX project, the devices are found and everything works properly, perhaps this problem depends on the security settings of JavaFX, or inability to use JavaFX is that jmf interfaces with audio and video devices?

thanks for the help
