OpenAM gives an Internal Server Error when the user tries to reset their password before the minimum password age

When OpenAM has a minimum password age established in OpenDJ with a Password Policy, the user will receive an Internal Server Error message in the XUI when they use Change Password instead of a message informing them their password cannot be changed due to the password policy.

Steps to reproduce:

1. Create a password Policy in OpenDJ with min-password-age set.
   • Run dsconfig command in OpenDJ bin
   • Select 27 for Password Policy
   • Select 3 to edit an existing password policy
   • Select 1 for Default Password Policy
   • Select 18 for min-password-age and change the value for the min-pasword-age
   • Select f to finish and save the changes that have been made
2. Login to the end user page.
3. Select "Change Password".
4. Change the User's password.

This will result in the user receiving an Internal User Error in the XUI even though the IdRepo logs show the following:

ERROR: An error occurred while trying to change password for identity: user.0
