> I'm running hadoop unit tests on a Ubuntu 12.04 64 bit virtual machine, every time I
try to run all unit tests with command "mvn test", the TestIPC unit test will fail, the console
will show "The forked VM terminated without saying properly goodbye. VM crash or System.exit
called?"
> To reproduce:

> $mvn clean install -Pdist -DskipTests
> $mvn test -Pdist -Dtest=TestIPC
