751658 - Crash/hang with SnowFX Java applet (which fails to load)

Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect)

Description

[Stephen Donner [:stephend] Not actively reading bugmail]

STR:

1. Load http://javaboutique.internet.com/Snow/ in a Firefox desktop nightly
2. Wait a while...

Expected Results:

Either the applet loads and initializes, or errors out gracefully (see below)

Actual Results:

We get the following:

load: class snowFX.class not found.
java.lang.ClassNotFoundException: snowFX.class
	at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
	at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source)
	at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)
	at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
	at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source)
	at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source)
	at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
	at java.lang.Thread.run(Unknown Source)
Exception: java.lang.ClassNotFoundException: snowFX.class

...which in turns either/both hangs the browser, and then crashes the plugin, here:

See also bug 592894, which the 1st stack references; there hasn't been activity there in over a year, and it looks like we're waiting on comment from the Oracle folks; as the bug is still present, and 100% reproducible, we should seek some traction.

Kev/Tomcat: do we have a contact who can look into this?
