WebStart and app title with 1.6 Update 2

We are seeing something very odd. Since applying update 2, IFF J2SE 6 is made the preferred VM (in Java Preferences), WebStart does not place the application title (from the JNLP INFORMATION block) as the visible name on the application menu and on the Dock tile. Instead, it places com.sun.javaws.Main as the name. If J2SE 5 (32-bit or 64-bit) is made the preferred VM the correct title is used.

The relevant portions of the JNLP file are:

<?xml version="1.0" encoding="utf-8"?>
<!-- JNLP File for Elluminate Live! application -->
<jnlp
  spec="1.0+"
  codebase=(REDACTED)>
  <information>
    <title>Elluminate Live!</title>
    <vendor>Elluminate Inc</vendor>
    <description>Elluminate Live! Virtual Room</description>
    <icon href="elive128.gif"/>
  </information>
  <security>
    <all-permissions/>
  </security>
  <resources>
    <property name="apple.laf.useScreenMenuBar" value="true"/>
    <property
	name="apple.awt.window.position.forceSafeProgrammaticPositioning"
	value="false"/>
    <j2se version="1.4+" initial-heap-size="32m" max-heap-size="96m"/>
...
  </resources>
  <application-desc main-class="com.elluminate.live.full.Main">
    <argument>-url</argument>
    <argument>(REDACTED)</argument>
  </application-desc>
</jnlp>

I also noticed that the javawebstart.version system property (displayed in our about box) is "javaws-1.6.0_07" when the J2SE 6 VM is first in the preferences list, and "javaws-1.5.0_16" when J2SE 5 (32-bit) is first. A previous post from Mike Swingler had stated:

I find this confusing, shouldn't I be seeing javaws-1.6.0_07 for javawebstart.version in both cases? Perhaps the property is wrong? Could it be showing the VM running the javaws code (which I would find counter-intuitive, I would expect the JWS version to be the version of the javaws code being run -- I would also be surprised if J2SE 5 could run the 6.0 JWS, I would expect it to require J2SE 6 JRE features).

It looks to me like a completely different version of JWS is being run depending on the Java Preferences, and the J2SE 6 one has problems with the application title. _______________________________________________ Do not post admin requests to the list.
