TestByteBuffer::testScopedBuffer is using the following code to skip some members of *Buffer it does not want to test:

            if ((!e.getKey().getName().contains("get") &&
                    !e.getKey().getName().contains("put"))
                    || e.getValue().length > 2) { // skip bulk ops
                //skip
                return;
            }

But, because of the 'return' this is skipping all of the trailing method when encountering the first non-tested method.
