CredentialHandler tag ignored for authentication

In Tomee 8.0.15 the CredentialHandler setup inside context.xml is not working:

    <Realm appName="SQLLogin"
           className="org.apache.catalina.realm.JAASRealm"
           roleClassNames="org.apache.openejb.core.security.jaas.GroupPrincipal"
           userClassNames="org.apache.openejb.core.security.jaas.UserPrincipal">
        <CredentialHandler className="org.apache.catalina.realm.MessageDigestCredentialHandler"
                           algorithm="sha-512"
                           saltLength="0"
                           iterations="1000"/>
    </Realm>

The indentical code is working up to 8.0.14.

Expected behavior:
If the user the enters the password "password" in a login screen they should be logged in, if the stored 'password' inside the credential store (e.g. data source, or properties file) equals: $1000$3dd6e976577884f22378edb795a86609f6f383a902dc4b11f66276fb992fbaf022e17788180050da92c0e881a9667a4799f0f8d8cfd3effcfd832c274cadb923

Observed behavior:
Acces is denied. Access will be granted however if the stored password (hash) is replaced by:
password

Im using JAAS with form based login.

I have created a test series with identical configurations:

TomEE 8.0.11 -> OK

TomEE 8.0.12 -> OK

TomEE 8.0.13 -> OK

TomEE 8.0.14 -> OK

TomEE 8.0.15 -> FAILS
