251918 - Hang on Java Applet with high CPU usage on scroll

Status: RESOLVED WORKSFORME

(Core Graveyard :: Java: OJI, defect)

Description

[Bill McGonigle (not currently reading bugmail; please contact directly)]

Go to the URL listed above.  Scroll the window.
Expected results: page scrolls normally
Actual Results: browser hang, high CPU usage, have to force quit

Mozilla 1.7 Mac OS X.3.4.
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-root_1.3.1_030912-19:52)
Java HotSpot(TM) Client VM (build 1.3.1_03-76, mixed mode)

With the new MRJPlugin from bug 197813 I get temporary hangs; control of the browser does return 
eventually, though any subsequent scrolls will peg the CPU for a while.

I'll attach a sample of Mozilla during a hang (Apple Plugin).

Above URL WFM with a recent Camino nightly.  Camino trunk build 2006101622 (v1.2+) running Mac OS 10.3.9 handled it, no hang, no crash.

Can't reproduce currently on 2.16GHz C2D; don't have access to old hardware; marking WFM.
