Changes

Upgrade of ZFS Storage Appliance from OS 8.6.8 to OS 8.7.4

Cause

Java incompatibility issue.

Prior to Java 8, Java did not support key sizes greater than 1024 bits for diffie-hellman keys. OS 8.7 SSHD requires keys larger than 1K.

Solution

The only option is to upgrade the system running SMU to Java 8.
