I think this is a test/machine issue. The test fails because it's expecting an OutOfMemoryError but didn't get it. The code just allocates something really big as follows, which doesn't guarantee an OOM if the machine has enough memory.

                switch(new Random().nextInt(3)) {
                case 0: dummy = new Integer[Integer.MAX_VALUE]; break;
                case 1: dummy = new double[Integer.MAX_VALUE];  break;
                case 2: dummy = new byte[Integer.MAX_VALUE][];  break;
