Documentation

Secure coding practices prescribe to use SHA512 with RSA for cryptographic use of hashing.

It is not recommended to use cryptographic algorithms and modes with known problems. For hashing, SHA512withRSA is the recommended algorithm.

Correct code example 
Signature.getInstance("SHA512withRSA");
