That would be expected as it is removed and there is no setter.

well that IS the suggested fix.
https://tomcat.apache.org/tomcat-8.0-doc/config/realm.html#Memory_Based_Realm_-_org.apache.catalina.realm.MemoryRealm
 "This attribute is deprecated. Set the algorithm on a nested

Unfortunately each version separate.

Hope this helps.
