Description
FULL PRODUCT VERSION :
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
An old version of our app wants to use JRE 1.4.  The JNLP file requests to
be run with a 1.4 JRE.  However, if Java 1.6.0_20 is installed, the 6.0_20
version of webstart downloads the application and launches the app with an
installed version of 1.4.  This is evident from:
      Java Web Start 1.6.0_20
      Using JRE version 1.4.2_10-b03  Java HotSpot(TM) Client VM



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
  To reproduce this bug just create a JNLP file that references a simple java class from a JAR-file, where <j2se version="1.4"> and run it with java web start (1.6.0_20).

1) Build the app from the supplied build source code and the build script
2) run the generated file "dist/jwstest.jnlp" with javaws (1.6.0_20)
3) See the jws console window

Run this with using the webstart in 1.6.0_18 and it works perfectly.

Release Regression From : 6u18
The above release value was the last known release where this 
bug was not reproducible. Since then there has been a regression.

                                    

Comments
EVALUATION

ParseUtil.encodePath(String, boolean) wasn't introduced until later 1.4.2 updates release, create a wrapper to take care of it.
