Resolution:

The exception is a known bug in an outdated JRE on the client machine(s). There are serveral JRE versions that are known to cause problems with Webstart, e.g. JRE 1.6u7 and 1.6u14.  In an updated JRE (the current version is 1.6u29), Webstart should work again.

To resolved the issue, you must clean the browser cache and the Java Webstart cache (execute "javaws -uninstall") on all client machine(s) that you wish to install the Manual Testing Client Webstart.

Please only use JRE 1.6 (not JRE 1.7 since this is currently not tested or supported).

Perform the following steps on all client machine(s) that you wish to install the Manual Testing Client:

1) Clean the browser cache

2) Clean the Java Webstart cache using the steps below:

     a) Load the Java Control Panel, Start | Control Panel | Java
     b) On the 'General' tab, select the 'Settings' button under the 'Temporary Internet Files'
     c) Then click 'Delete Files...' on the Temporary Files Dialog
     d) Agree to delete all Applications, Applets and log/trace files

3) Execute 'javaws -uninstall' from the command prompt to uninstall the current java version on the client machine

4) Install JRE 1.6 update 29 (Java SE 6 Update 29) from here:

Note: Any of the JRE 1.6 versions should work but please do not use JRe 1.6u7 or 1.6u14
