Adding or Updating an Account should not throw NumberFormatException if minimum password length is not configured

Current Situation

When creating a new account or updating an existing account without setting a minimum password length, the default value should automatically be used. In some cases a NumberFormatException occurs, when such an account is added or updated.

Desired Behavior

When creating an account or updating an existing account without setting a minimum password length, the default value should automatically be used. A NumberFormatException should not occur for the custom minimum password length, even if not set, as the default value should be used in that case.

Workaround

In cases, where the NumberFormatException occurs, the setting of a custom value for the minimum password length resolves the problem, Customers who don´t want to deviate from the configured default value can set the same value for the custom value.
