Default After update to Core 47153, all CRC checks using external sfv files falsely fail

After jDownloader2 updated to Core 47153, all CRC checks using external sfv files fail, even though the files have correct checksums (verified with Total Commander 10.52).

Normally I download files, generate .sfv files for them with Total Commander 10.52, redownload everything and let jDownloader2 verify against created files (setting SFV / CRC check when possible). After update to Core 47153, it went from 0% failure rate to 100% failure rate.

Steps to replicate:
Download for example **External links are only visible to Support Staff****External links are only visible to Support Staff** and let it verify against this sfv file 100MB.bin.sfv (either automatically with SFV / CRC check when possible or manually by right-click > Other > Start CRC-Task!):

; Generated by WIN-SFV32 v1.0
; (Compatible: Total Commander 10.52)
100MB.bin 4B282398

I am getting 'Download failed' either way. Total Commander 10.52 says that the checksum is correct.

However, when I right-click on the downloaded file in jDownloader2, Open Properties Panel, enter '4B282398' in the checksum field there, and then choose Start CRC Task, jDownloader2 says [CRC32] CRC OK. So it looks like for some reason it can no longer read sfv files correctly?

@xanthia: Thanks for the report! found the cause and will be fixed with next core update
Issue has been caused by introduction of CRC32C support that has same length as CRC32.

I believe this has been fixed with a core update already (at least it is again working on my side).
