Checked the exact outputs from Guava & Apache by following code.
`byte mask = (byte) 0xFF;
long length = 12345678987654332L;
byte[] data = "data".getBytes();
// Guava implementation
Hasher hasher = Hashing.murmur3_32().newHasher();
long guavaResult =
hasher.putByte(mask).putLong(length).putBytes(data).hash().padToLong();
// Commons implementation - use the right byteBuffer size and byte order
ByteBuffer byteBuffer = ByteBuffer.allocate(1 + 8 + data.length)
.order(ByteOrder.LITTLE_ENDIAN) // Important for long values
.put(mask)
.putLong(length)
.put(data);
byteBuffer.flip(); // Reset position to start
byte[] bytes = new byte[byteBuffer.limit()];
byteBuffer.get(bytes);
long commonsResult =
Integer.toUnsignedLong(MurmurHash3.hash32x86(bytes));
Assert.assertEquals(guavaResult, commonsResult);`
