ADDITIONAL SYSTEM INFORMATION :
windows 8.1

A DESCRIPTION OF THE PROBLEM :
I load the htm file on the webView.
Change the file loaded several time through the method webView.getEngine().load(new File(<path>));.
After several changes (3-4) the CPU usage of the software from 0-1% goes to 20-25% stable until i close the webView.
If i keep the page open for 10 minutes or more the JVM crashes.
