Hash, displace, and compress: Perfect hashing with Java
...sounds like quite a niche use-case, but I agree that I cannot think of any other stream-hashing library. I hoped https://github.com/OpenHFT/zero-allocation-hashing would do, but it doesn't. However, https://github.com/OpenHFT/Chronicle-Bytes has xxHash if that's your thing.

UltraLogLog: A more space-efficient alternative to HyperLogLog
The newest version of the hash4j Java library (https://github.com/dynatrace-oss/hash4j) introduces UltraLogLog, a new data sketch for approximate distinct counting that uses 22% less space than HyperLogLog using 6-bit registers to achieve similar estimation errors.
