PolicyList to AuthorizationServerPolicyList is confusing us

We’re trying to update our Java Okta SDK from 2.0.1 to 4.1.1, and our code that calls client.listPolicies(“PASSWORD”) is now returning AuthorizationServerPolicyList instead of PolicyList. The confusing part is that AuthorizationServerPolicyList appears to be incompatible with PasswordPolicy, which then leads to our code crashing. Is there some other way now to obtain a list of password policies?
