FULL PRODUCT VERSION :
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
When a java 1.6 32 bit is installed and a java 1.7 64 bit is installed, javaws creates shortcuts to the 32 bit version. This raises a problem with users who have a 32 bit version of java installed previously and install java 1.7 64 bit to try to upgrade and are unable to run a web start application because the shortcuts created by javaws always point to the 32 bit version which was still running 1.6

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Install java 1.6 32 bit
install java 1.7 64 bit

javaws -import http://path_to_jnlp.jnlp

If the jnlp has <shortcut online="true">
       <desktop/>, the shortcut that is created always points to %Systemroot%\SysWOW64\javaws.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Honestly I'm not sure. There needs to be a way to get a shortcut to the 64 bit version of javaws for applications that support / need it.
ACTUAL -
javaws always creates a shortcut to 32 bit java if both 32 and 64 bit are installed.

no way to get a 64 bit java shortcut created by javaws.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
install both java1.7 32 bit and java1.7 64 bit.
