FULL PRODUCT VERSION :

Java(TM) SE Runtime Environment (build 1.8.0_60-b27)


ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
We are using JavaFX Ant Tasks to build web start package.
The ant file will generate a jnlp file.
We pub all the library in "lib" folder.
The generated jnlp works fine, since it used correct file separator like:

<jar href="lib/adapter-1.0.0.jar" size="2759674" download="null" />
---------backward slash

However, recently we upgraded to jdk8u60, web start complains URISyntaxException: Illegal character in path at index 11: /public/lib\xxxx.jar.
And in jnlp file, it is using

<jar href="lib\adapter-1.0.0.jar" size="2759674" download="null" />
----------forward slash.




REGRESSION. Last worked in version 8u40

ADDITIONAL REGRESSION INFORMATION:
java version "1.8.0_31"

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
simply use JavaFX Ant Tasks to build web start package

EXPECTED VERSUS ACTUAL BEHAVIOR :

the jar path in jnlp using backward slash
<jar href="lib/adapter-1.0.0.jar" size="2759674" download="null" />
ACTUAL -
the jar path in jnlp using forward slash
<jar href="lib\adapter-1.0.0.jar" size="2759674" download="null" />
