ssl in chat example
-------------------
Key: DIRMINA-728
URL: https://issues.apache.org/jira/browse/DIRMINA-728
Project: MINA
Issue Type: Bug
Components: Example
Affects Versions: 2.0.0-M6
Environment: Ubuntu 9.04, Sun Java 6, m2eclipse
Reporter: Lars Bohl
The SwingChatClient (org.apache.mina.example.chat.SwingChatClient.java) won't
work with SSL activated.
How to reproduce:
- start the server from the chat example (SwingMain.java)
- start the client from the chat example (SwingChatClient.java)
(i checked out the mina source, which includes the examples, via svn, and set
up an ad-hoc m2eclipse project for these first 2 steps .. )
- click "Connect" in the window opened by SwingChatClient.java
- in the Connect dialogue, select "Use SSL" and click "OK"
Here's the output I get (I put the example classes in packages named
"springBastelKurs.bastelArtefakt" and "springBastelKurs.bastelArtefakt.client"):

Note: I met elecharny in #mina and he was able reproduce the error. He thinks
that the bug is probably not in SslFilter, since he's using it a lot and it
works fine.
