Liveconnect java plugin fails to load class (webct)
Last modified: 2009-02-24 14:13:06 EST
Description of problem:
The new liveconnect plugin crashes on http://elearning.agsm.edu.au
Version-Release number of selected component (if applicable):
NB - **I'm testing this on F9, not rawhide**. I get the same result if I take the srpm from koji and rebuild it myself.
How reproducible: Always
Steps to Reproduce:
1. go to http://elearning.agsm.edu.au/
2. Allow the popup
Popup/java tester window opens, then browser crashes
Not crash. Popup should auto-close
The 'standard' F9 gcjwebplugin would open the popup window, but not close it. It closes on winxp, so I assume that theres something that is meant to close the extra window if the java version test passes.
ICEDTEAPLUGIN_DEBUG=1 firefox -g
log is attached.

Poking arround with this a bit, it looks like the reason that its failing to load is because the applet has:
<param name="cache_archive_ex" value="browserchecker_applet.jar;preload;1190988167141">
which doesn't see to be understood. So thats one problem (thats not new, but I was hoping that it was fixed with the new liveconnect stuff), but the plugin still shouldn't crash.
The plugin under linux tries to load /webct/jar/com/webct/platform/tools/browserchecker/applet/BrowserCheckerApplet.class while Sun java on windows loads /webct/jar/browserchecker_applet.jar
- once the test has part it won't try again without restarting the browser; presumably theres a session cookie being set
- The applet param means that java caches the applet, so you won't see the network request for it again unless you clear the cache via the java control panel on windows
... and now it doesn't crash for me, even though I didn't change anything. Still doesn't work, though.
Yes, cache_archive_ex is still unsupported unfortunately. It is on my list though, and I plan to start work on it shortly. Corresponding upstream bug:
*** Bug 469098 has been marked as a duplicate of this bug. ***
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
More information and reason for this action is here:
Should be fixed in the latest release.
