JDK-7195948 - IE 10 + Windows 2012 runs reloaded plugin in 2nd JVM instance
Description
Steps to reproduce:
1. Install the 7u40-b39 promoted build.
2. turn java console on
3. Access page http://kgb.us.oracle.com:8080/LiveConnectTest/html/testMultipleApp.html
4. Accept the unsigend code sec warning dialog
5. If you see a lot java console showing up, then the issue is reproduced.

Expected:
with previous jre release, looks like there's only one jvm instance there.

There is no functional regression, so mark it as p4.
Comments
This is a duplicate for JDK-8023095. Tried with 8u40-b20 and only 2 instances are created. This is expected behavior since one of criteria to spawn a new JVM instance is the number of threads exceeds 50 (this default could be changed by setting deployment.system.maxAppletThreadCount in deployment.properties) and every applet creates at least 3 new threads. Thus, no more then 16 applets could coexist in the same JVM. The tests creates 27 applets that results in 2 JVM instances are created.

Ok, then it seems like a x86 problem - because I tried win7 64 bit for IE/FF/Chrome - and it works fine, only one jvm is created.

Could you please try 7u45-nightly-#253 on Windows 7-x86/Chrome? Just open the link, and wait there for like 1 ~ 2 minutes, you should see a lot of java console dialogs eventually. I just reproduced on my local vm.

CNR for latest 7u45 and 8.

I was not able to reproduce this issue for latest 8, seems like it's already fixed, and the problem was that we could not attach to existing JVM.
