For those of you who know CR servers (i don't know if this feature was implemented on other IRCds), you will know of channel mode +j.
- Usage: MODE <room> +|-j
- j - Java Clients Only
- This command allows you to have only java clients and sellected legacy IRC clients enter the specified channel. $&
For this mode to take effect you must set a key. $&
For IRC clients to enter the channel they must supply the key, or be invited into the channel.
- Privilege: Channel Operator

What i'm wondering, is how does the IRCd makes the difference between Java clients and others? Is it a 'hidden code' in CR's java applet, or what?
