Port 9999 already in use exception - examples in eclipse

Hi - I’m attempting to run the simple examples via ecplise - with the CloverGUI plugin.

I’m getting:

Error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 9999; nested exception is:
java.net.BindException: Address already in use: JVM_Bind

note - port 9999 is not being used by another process - honest.
I am on windows, and can use netstat -a to verify port 9999 is not used before I start to run the example. At the point the example runs I see that port is used, and then is freed when I close Ecplipse.

As a newbie I was surprised to see it using a port at all… but hey…

environment:
Ecplipse Europa 3.3.2
Vista Business
Clover 2.0.2

any help appreciated !

thanks,
Oli.

ok - …so there was a process hanging on to 9999 (…hangs head in shame)
all good now -
