When creating numerous (depends on what else is running in the application) WebViews and pointing them at complex web pages, the VM eventually crashes with:
#
# A fatal error has been detected by the Java Runtime Environment:

I do have a fairly simple application that reproduces the issue. It involves creating 50 WebViews pointed at the JSPlum kitchen sink demo and destroying them with the test repeating every 60 seconds. While this is somewhat extreme, the VM still should not crash. In my real application, the crash happens with as few as 6 web views (which is extremely likely in my application).
