>On that particular place, this is the default CRC32 class which is Integer only. So, the question I was wondering about is to know if it is normal that a CRC32 value can be bigger than an integer. Because, if that is the case, this should generate an error at calculation time as the CRC32 value calculated wouldn't fit at first in the property declared integer.

If it's your crc32 class which returns an Integer, then that value is impossible.
