Java APIs

I have problems using RMI between linux and windows.
This is my scenario:
- Server running on linux pc
- Clients running on linux and windows PCs

When a linux client disconnect, first time that server try to call a method of this client, a rmi.ConnectException is generated so server can catch it, mark the client as disconnected and won't communicate with it anymore.

When a windows client (tested on XP and Vista) disconnect, no exceptions are generated (I tryed to catch all the rmi exception), so server cannot know that client is disconnected and hangs trying to communicate with the windows client.

Any ideas?

Thanks in advance.
