They were ensuring  that *no* *general* exception occurred.  Unluckily in many test runs some 
completely unrelated, and absolutely harmless exceptions  are printed.  The torturing of 
browsers/java by repeated kill -9 do this.

So Although at first the tests were "pessimists" == everything have to be ok. Now they are 
"optimistic" == just the core of reproducer passed.

Although I'm fan of "pessimistic"  tests. In this case it caused the great instability of engine - 
random failures each run.
