> When bumping the Sidecar version used in Analytics, an issue surfaced in the 
> Analytics implementation of XXHash32 where we cast the hash value to long, 
> and the negative sign is forwarded causing the incorrect hash value to be 
> returned. 
> is not masked and this causes the negative sign to be forwarded. Other 
> implementations (for example commons-codec) mask the hash value correctly.
