I have managed to make a working demo of WebView running inside Oracle Forms. I have attached the source Java files and FMB for example. This works - except the fact, that it takes more than 5 minutes to load the WebView. I have run an analysis of this issues with jvisualvm.exe, of which I have attached an export of the profiler run for the CPU, where it's very clear, that an excessive amount of time is spent in sun.net.http.KeepAliveCache.run() when loading WebView in this configuration - which also was, what I could see live monitoring the "hang" of the Forms app.

My main reason for testing JavaFX 2.0 is this very point, so I hope, that something can be done about this. Please take a look at this.
