> 1. Several "Arrays.equals(arg1, arg2)" in the testAsShortBuffer, testAsLongBuffer and testAsIntBuffer method miss assertTrue() statement. 
> 2. When the missed asserts are added, four more test cases fail on Harmony, look more inside, the evil is not in the ByteBuffer but in the helper methods of ByteBufferTest - short2bytes, int2bytes(int value, ByteOrder order) and long2bytes(long value, ByteOrder order), These methods try to convert a short/long/int value to byte arrays with the given ByteOrder, but if the ByteOrder is set to ByteOrder.LITTLE_ENDIAN, an error may occur. For example, a short value 0x0102 should be converted to byte[2]{02,01} with ByteOrder.LITTLE_ENDIAN, but it returns byte[2]{01,00} now. I will attach patch soon.
> The test result keep same on RI before and after these bug fixing.
