I keep getting that. Even if I try to change a thread's name I get that error. Any workaround?

It seems you're trying to set a new security manager in line 74 in Main.java. You're not allowed to do that.

[edit:]
There should be no work-around. If you find one, you've found a security flaw in java.

I think he got some totally different security Exception (when setting the thread's name), and then tried to remove the security manager with System.setSecurityManager(null).



It shouldn't be a problem to set the name of a Thread in its constructor.

yeah thats exactly what happened.. Apache MINA tries to set the name of a thread and it gave an exception. I can't go and edit the MINA libraries..

MINA also resolves hostnames, which is illegal in the sandbox, so you can't connect to your own host.

It's just sad how MINA criples itself.
