Questions about using 1.5.2-SNAPSHOT

[Simon . Temple]

I have code that supports an embedded DS in JBoss.  The following imports that 
were valid in 1.5.1 no longer appear to be valid in 1.5.2.

import org.apache.directory.server.changepw.ChangePasswordConfiguration;
import 
org.apache.directory.server.configuration.MutableServerStartupConfiguration;
import org.apache.directory.server.core.configuration.ShutdownConfiguration;
import org.apache.directory.server.core.configuration.SyncConfiguration;
import 
org.apache.directory.server.core.partition.impl.btree.MutableBTreePartitionConfiguration;
import 
org.apache.directory.server.core.partition.impl.btree.MutableIndexConfiguration;
import org.apache.directory.server.dns.DnsConfiguration;
import org.apache.directory.server.jndi.ServerContextFactory;
import org.apache.directory.server.kerberos.kdc.KdcConfiguration;
import org.apache.directory.server.ldap.LdapConfiguration;
import org.apache.directory.server.ntp.NtpConfiguration;

Could you confirm this and advise me of where I can find information on these 
changes/refactoring?

TIA
