FULL PRODUCT VERSION :
build 1.6.0_10-beta-b25

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

A DESCRIPTION OF THE PROBLEM :
I launched a JWS application with 1.6 update 6 and it worked fine.
Then i tried to launch the application using update 10, but the launch failed with an exception

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run a JWS Application under 1.6 update 6(i tried it with this version, because the equinox launcher does not work with update 7)
The client.jnlp is beeing auto generated using the specified parameter in the querystring.
<jnlp spec="1.0+" codebase="http://localhost:8020/webstart/" href="client.jnlp?edition=Client&version=4">
2. The application works fine.
3. Try to run the jws application with 1.6 update 10-->Could not launch the Application.
The Stack Trace is:
java.lang.Exception: cache failed forhttp://localhost:8020/webstart/client.jnlp?edition=Client&version=4
at com.sun.javaws.Launcher.updateFinalLaunchDesc(Unknown Source)
at com.sun.javaws.Launcher.prepareToLaunch(Unknown Source)

at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
at com.sun.javaws.Main$1.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

If i remove the query String(href="client.jnlp" instead of href="client.jnlp?edition=Client&version=4" and add a few workarounds to the Servlet, which generates the JNLP file(use a hard coded version and edition) the application works.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It should be possible to launch the application with 1.6 update 10 as well.
ACTUAL -
Could not launch the application: Cache failed for {url.of.jnlp.file}

REPRODUCIBILITY :
This bug can be reproduced always.
