OS X 10.5.6, Safari 3.2.1 hangs when second applet loaded is signed applet

Question

Dear Forum,
I've been investigating a customer's problem. She is trying to use our
VoIP applet, but it continuously freezes Safari when the Trust dialog shows.
A "Force Quit" is necessary.
I managed to reproduce the problem consistently on
- PowerMac7 OS X 10.5.6 (Build 9G55)
- Architecture: ppc
- Safari 3.2.1 (5525.27.1)
- JVM 1.5.0_16 from Apple
The problem is persistent when:
- the signed applet is loaded as second applet in the browser
- the signed applet is cached by the JVM
Our customer uses:
- Mac Book ProOS X 10.5.6
- Safari 3.2.1
- JVM 1.5.0_16 from Apple
This problem does not occur on:
- Mac OS X 10.4.11 (Mac Powerbook G4)
- Safari 3.2.1 (4525.27.1)
- JVM 1.5.0_16 from Apple
and not on:
- MacBook Air, OS X 10.5.6, 1.6 Ghz Intel core 2 duo
- Safari Version 3.2.1 (5525.27.1)
- JVM 1.5.0_16 from Apple
Steps to reproduce the problem:
Launch Safari.
In (first) page/tab go to
http://www.javatester.org/version.html
(this uses a non signed applet)
Open a second tab. Here go to:
http://ukapi.phonefromhere.com/talk/vtop2.xsql?key=01612884242
This is a signed applet that will ring our office over VoIP.
Click the "Trust" button (signed by PhoneFromHere).
As long as this applet isn't cached by the JVM this will work, so
the first time you will succeed.
Now Quit Safari (not "just" close all Safari windows, but a "real" quit) and repeat the exercise.
The second (and next) time this will fail (only if the signed applet is loaded as second, so the order is important)! This keeps failing until I go (back) to the Java Preference window (via Finder) and explicitly delete the cached files.
The URL will work when loaded first (cached or not).
Some diagnostics, that might help:
I configured the Java Preference window to "enable Logging, Tracing and Show applet livecycle exceptions".
When the applet fails to load (and Safari freezes/hangs), the last few records of the plugin150.log are:
<message>basic: Loading http://ukapi.phonefromhere.com/talk/lib/pfh.jar from cache
<message>basic: Reading cached JAR file from JRE 1.5 release
<message>basic: Certificates for http://ukapi.phonefromhere.com/talk/lib/pfh.jar is read from JAR cache
<message>security: Loading certificates from Deployment session certificate store
<message>security: Loaded certificates from Deployment session certificate store
<message>security: Checking if certificate is in Deployment session certificate store
(and then nothing)
whereas when it succeeds to load, as soon as I click the "Trust" button, it's say:
<message>security: User has granted the priviledges to the code for this session only
The Report is a bit too long to port, I'll include the same text above when sending it.
Model: PowerMac7,2, BootROM 5.1.3f0, 2 processors, PowerPC 970 (2.2), 1.8 GHz, 2 GB
To cut a long story short? Is this a know bug (I couldn't find anything, but you never know)? Does anyone have any ideas how to fix this?
Thanks, Birgit

Answer 1

I have the same issue now after downgrading my Flash plugin. I downgraded from 10 to 9 latest because I like using Camino and for some reason Flash 10 doesn't play nice with Camino. But all of a sudden as I use Camino 2b2 for everyday and Safari 3.2 for banking and such, the browser hangs requiring a forced quit when I close it. I've re-installed the browser twice now with all the previous folders, and preferences erased and caches emptied. I even when to re-installing 10.5.6 and it still crashes, it's odd. Maybe 10.5.7 will address this.
