I'm locking and unlocked the lock screen.
Unlocking via
boolean result = devicePolicyManager.resetPassword( "", 0 );
devicePolicyManager.lockNow();
In Lollipop, it turns the screen off (expected) and when you turn it on - instead of the swipe screen - it display the numeric keypad but you don't have to enter the correct PIN or a PIN to unlock -
This same code works in pre Lollipop by displaying the swipe screen once and then fully unlocked after that.
Is this a bug in Lollipop?
