What version of the product are you using? On what operating system?
JCEF version: 3.2171.1902.113
CEF Version:      3.2171.1902
java version "1.7.0_02"
Java(TM) SE Runtime Environment (build 1.7.0_02-b13)
Java HotSpot(TM) Client VM (build 22.0-b10, mixed mode, sharing)
Windows 7 64-bit

Please provide any additional information below.
Using the attached classes, launch the MainFrame class.  MainFrame has been 
modified to add a "NEW TAB" button which launches the TabFrame class.  TabFrame 
is a stripped down MainFrame that receives the same client from MainFrame and 
simply creates a new browser in a new window.  Opening multiple windows works 
but clicking each window exhibits varying behavior (flicker, does not move to 
foreground).  The application crashes via a combination of opening multiple 
windows (4-5), quickly clicking varying works for focus and closing/opening 
others.  There seems to be a correlation with the closing of a window that 
causes the crash but I cannot pinpoint the issue specifically.

If it helps to reproduce, I seem to be able to reproduce this more consistently 
when there are two TabFrames in addition to the one MainFrame.  Have all three 
windows overlapping in some manner.  It seems to help being able to see the 
close button of at least the TabFrames.  Then, while dealing with the TabFrames 
only, attempt to select (one single click) the TabFrame that is behind the 
foremost TabFrame, when it fails to come to the foreground attempt to close 
that same TabFrame via the X [Close} button.  If it closes normally, repeat by 
opening another TabFrame and attempt to select the TabFrame behind the foremost 
TabFrame.

I have raised a similar issue here:

snippets. Please check and update if anyone is able to help with the crashing 
issue on browser close.
