Priority: P3
Bug ID: 1177
CC: unassigned at icedtea.classpath.org
Assignee: omajid at redhat.com
Summary: Blackboard Collaborate - Fatal error trying to verify
jars
Severity: normal
Classification: Unclassified
OS: Linux
Reporter: pietila.meghan at gmail.com
Hardware: x86
Status: NEW
Version: 1.2
Component: NetX (javaws)
Product: IcedTea-Web

Blackboard Collaborate sessions will no longer load.

On September 20, sessions were working. On September 24, they were not. No
updates were run on the client computer during this time (so presumably
Blackboard Collaborate jars were changed in some way in the interim, or their
certificate expired).

The following is a url to a Blackboard Collaborate page with a link to a test
session that causes this problem:

JARs download, then error (stacktrace follows)

Hi Meghan, thanks for the bug report.

I'm unable to reproduce this using Java 7 + ITW 1.2 or 1.3. What version of ITW
and what Linux distribution are you using ?

When you say 'test session' you are referring to links in the section "STEP 2:
Configuring your system", correct ?

Perhaps you can also try clearing the cache with javaws -Xclearcache or
removing ~/.icedtea. If it still fails, please run with
ICEDTEAPLUGIN_DEBUG=true javaws <location of jnlp> and give the resulting log
here.

Thanks,
- Adam.

I am running Ubuntu 12.04, ITW 1.2, and Java 1.6.0_24. Ran all Ubuntu updates
yesterday.

By 'test session', I do mean the links in "STEP 2: Configuring your system",
sorry for not being more clear. Specifically, version 12 is the one I am
attempting to use.

I have tried clearing the cache both through removing ~/.icedtea and through
the IcedTea Control Panel. Just to be sure I can run javaws -Xclearcache as
well.

Log to follow.

And... it works this morning. I had not tried clearing my cache since running
the Ubuntu updates yesterday - maybe I picked up something in the updates that
fixed the problem, but needed a clean cache. I had run rm -rf ~/.icedtea/cache
first thing today.
