[midPoint] password storage method "hash" and users with empty password

[Marco Benucci]

Hi,

we are running midpoint 3.6 and we would like to switch the password 
storage method from enrcyption to hash.
Now, if we create a new user with an empty password from the gui, we got 
this error:

java.lang.IllegalStateException: Subresult 
com.evolveum.midpoint.model.impl.lens.ChangeExecutor.execute of 
operation com.evolveum.midpoint.model.api.ModelService.executeChanges is 
still UNKNOWN during cleanup; during handling of exception

with encryption method this error does not happen and one can create a 
new user from the gui without add the password.

Is this a bug?
