Guard against EOF when reading in FileBridge.

                    int len = Memory.peekInt(temp, 4, ByteOrder.BIG_ENDIAN);

                    while (len > 0) {

                        int n = IoBridge.read(mServer, temp, 0, Math.min(temp.length, len));

                        if (n == -1) {

                            throw new IOException(

                                    "Unexpected EOF; still expected " + len + " bytes");

                        }

                        IoBridge.write(mTarget, temp, 0, n);

                        len -= n;

                    }
