For context, Oracle has assigned CVE-2015-0478 for the missing hardening
in the default JCE implementation:

This case is similar to libgcrypt, I believe: no key leaks have been
attributed to this implementation, the change is purely hardening in
this sense (and I would not have assigned a CVE ID to this).
