A DESCRIPTION OF THE PROBLEM :
Our java application uses JavaFX’s WebView to load a single page application which should be available while the user is offline.

The single page application will be delivered by a jar file. This case works without any problem by using JDK8u51, but something changed in case of JDK8u60.
Our relative referenced javascript files (inside the same package) will not be loaded by the WebView and therefore our application doesn’t work.
