FULL PRODUCT VERSION :
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) Client VM (build 25.60-b23, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
We wanted to install JDK 1.8.0_60 x86 on multiple computers (windows 7 64bits and 32 bits) having only JRE 1.8.0_60 x86 installed.
Our goal was to analyze our JNLP application runtime with jvisualvm.

Before installing the JDK, the JNLP application behaves normally.

After installing the JDK, launching the application with "javaws.exe app.jnlp" results in the creation of hundred of javaws.exe instances running and freezing the computer. Of course the JNLP application never starts.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
- Take a PC with windows 7 32bits or 64 bits
- Install the JRE 1.8.0_60 x86
- Make sure no other JRE is installed
- Install the JDK 1.8.0_60 x86
- Launch an usually working JNLP app

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The JNLP app should just start normally
ACTUAL -
Multiple instances of "javaws.exe" are created, crashing the computer.
The app doesn't start.

REPRODUCIBILITY :
This bug can be reproduced always.
