FULL PRODUCT VERSION :
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
ADDITIONAL OS VERSION INFORMATION :

Windows 7 Ultimate 64 bit SP1
A DESCRIPTION OF THE PROBLEM :
WebEngine does not load a resource file ( javascript, css, image) when this file is referenced from within a html file and when the resource files are packaged in a jar file.
For example this html file that references a javascript file foo.js and loads an image file test.png :
<===== main.html ======>
<html>
<head>
<script type="text/javascript" src="foo.js"></script>
</head>
<body>
This is my editor
<p>
<img src="test.png" alt="test1"/>
</body>
</html>
<=======End of main.html ==============>
The javascript file foo.js in the root folder
<=====foo.js ==============>
var foo;
function foo()
{
}
<=========End of foo.js ======>
Let have an image file test.png
Here the java class test:

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Bundle the provided java class and the resource files in a jar file,
run java -jar file.jar
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The web page is loaded from the html file
The image is loaded from png.test
The foo.js is loaded and the foo() function is defined
ACTUAL -
The web page is loaded from the html file
The image is not loaded
The javascript file is not loaded and the foo() function is not defined
REPRODUCIBILITY :
This bug can be reproduced always.
