FULL PRODUCT VERSION :
Plugin-Info:
Java 2 Runtime Environment, Standard Edition 1.4.2_04
Standardversion der virtuellen Maschiene 1.4.2_04-b05
Java Plugin 1.4.2_04
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
EXTRA RELEVANT SYSTEM CONFIGURATION :
IE Version6 .0.2800.1106.xpsp2.030422-1633
IE Update Versions: SP1, Q832894; Q330994;
A DESCRIPTION OF THE PROBLEM :
Resizing an applet using JavaScript causes IE to freeze for up to 10 seconds. This problem only apears in JavaPlugin 1.4 2_04 with IE 6. On Mozilla Firefox 0.8 the applet is running fine. With JavaPlugin 1.4.2_03, 1.4.1_02, 1.3.1_08, 1.3.1_05 resizing works fine in both browsers.
I think, there is a problem in the communication JavaScript to Java, because if I call some dummyMethod which only prints out some trace messages, the same problem occurs.
See the section "Source Code"
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) create and compile the applet
2) create applet page an place it into the same folder like compiled applet 3) class
4) show the page in IE
5) resize the browser window.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Reizing without freezing the browser window.
ACTUAL -
Sometimes resizing is possible, but very offten the Browser is not reponding for up to 10 seconds, while the CPU load is 100%.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
There are no error messages in the console.
REPRODUCIBILITY :
This bug can be reproduced often.
