[4.4 flashed] Root password "recovery" not accepted by sshd in recovery mode

XA2 4.4 flashed
Don’t know yet if this is a bug or only me.
I booted in recovery mode (fastboot boot hybris-recovery.img)
Pressed “5” to launch sshd

When trying to log in (ssh root@ from another terminal, the password (recovery) is not accepted.

hybris-recovery.img from SFOS_4.3.0.15 works though.

Did someone try this?
Or did nobody have the same issue?
