The attached zip file contains the test case and the hs_err file (which I will also attach to this JIRA for ease of viewing).

The following was sent to me by Igor. I have not yet had time to reproduce it, but will try later today:

Could you please try to:
   1) unzip attached zip file
   2) Make sure java console is set to show always
   3) open MultiAppInPlace.html and wait for 2 applets to start. This will bring 2 consoles - close any of them by clicking on "X".
       Note that closing second console does not crash JVM

In my case one applet disappears due to VM crash. I am using recent deploy scrum build i think.

I thought it is linked to custom preloader as this is what make these applets different. But turns out that other VM can crash too.

hs_err file is in the zip too. Below is stack from it.
