Hot Swap not working on several servers

Hi,

it downloaded a trial of IntelliJ 12 and test it with an Tapestry Project (build from an Maven Archtype). I will use the hot swap feature and tried severel Server. I configured the servers (default configuration with enabling hot swap) and started the debug mode

I have tried: Tomcat 7, TomEE and Jetty 8 (I did not get Jetty 9 working with IntelliJ !)

For all serves i got the followin message after changing something:

Hot Swap failed

TomEE: hierarchy change not implemented;

TomEE: Operation not supported by VM

I try to use hot swap the first time, so i am not familar with it. So maybe i did something wrong!? Or is there a general problem?

Thank you

Sascha
