When the randomly chosen amount of code cache is not enough to start the compiler(s) it should print that message, when it is enough to start both compilers, you don't see that message. The important thing is that there is no crash when compilers are trying to reserve code cache (they should be just shut down).


What I wanted to verify with above expected crash is that current number are not enough for the compilers and we saw the output is containing that "Codecache is full" message. 

Now we can claim that this message is there in the log output and test passes successfully.
