FULL PRODUCT VERSION :
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) Client VM (build 23.1-b03, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Windows 7 64bit and 32bit
Windows XP 32bit

EXTRA RELEVANT SYSTEM CONFIGURATION :
JNLP and the Application is provided by Apache HTTPD using SSL/HTTPS on port 8400

A DESCRIPTION OF THE PROBLEM :
We're deploying our Webstart application to many users. Since we need to serve multiple services on one host, we have to use https non-standard port 8400. Doing so we also can grant access directly in the firewall system.

We had no plroblems in Java 1.6 but siche more and more users were updating/switching to Java 7, the following issue gets reported more and more.




REGRESSION. Last worked in version 6u31

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
* confugure httpd to use HTTPS and Port 8400 (maybe also other ports)
(HTTPS on 443 is OK)
* start the application using webstart: javaws https://...:8400/jws/App.jnlp

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The Application starts as usual (as youre using JRE 6):
* Java 6 Splash screen
* Download of JNLP File by the Webstart process
* Download and Start the application described in the JNLP
ACTUAL -
* The Java 7 splash is shown
* The following Error is reported see below
