Description
FULL PRODUCT VERSION :
from JRE:
Java Plug-in 10.25.2.17
Using JRE version 1.7.0_25-b17 Java HotSpot(TM) 64-Bit Server VM
ADDITIONAL OS VERSION INFORMATION :
Windows 7
A DESCRIPTION OF THE PROBLEM :
When loading and refreshing a page with a number of applets, multiple Java console windows open. After some time of refreshing the pages, pausing starts to happen.
I have a simple example with 10 applets that demonstrates the issue. I will provide it here.
REGRESSION. Last worked in version 6u45
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create an HTML page with an 10 or more applets. Open the page in a browser and refresh the page often. Make sure the Java console window is open. After refreshing many times, you start to see multiple console windows opening, as well as pausing while refreshing.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect to see one console window open, displaying the teardown and buildup of the applets.
ACTUAL -
I see multiple console windows opening, and each window continuing to report results.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
I see these error messages in the console, though I have no idea if they are really related or not.
