Description

There are some common messages that can be shared by filters and transport implementations like in the SSL filter for handling secured and unsecured messages. Sometimes having this in the target requires JDK 1.5 dependency even if these features are not used. Here's a thread of converstation between Trustin and I about this speciifcially dealing with the SSLFilter and the LDAP protocol provider:

(21:19:02) trustin: StartTLS needs events that notify when the current session is secured or unsecured.
(21:19:14) trustin: SSLFilter emits them.
(21:19:21) akarasulu: right but can't we check the name of the class
(21:19:27) trustin: LDAP provider translates them into ExtendedMessage.
(21:19:46) trustin: We can do that.
(21:20:24) akarasulu: like message.getClass().equals( "org.apache.mina.filter.SSLFilter.SSLFilterMessage" );
(21:20:34) akarasulu: is this way bad?
(21:20:51) trustin: I think it's bad. We'd better define some core messages in mina-core.
(21:21:06) trustin: in... org.apache.mina.message.SessionSecured
(21:21:17) trustin: SessionUnsecured something like that.
(21:21:37) akarasulu: yeah that's better you're right
