Richard Achmatowicz commented on JGRP-1087:
-------------------------------------------

I wrote a small program which allocated sockets, closed them and the reallocated them on the same port, 10 times in a row. 
There is no problem doing this on Fedora. So the problem had to be somewhere in the JGroups code.

One problem was that the following was being called:
ct1 = new ConnectionTable(...) ;
ct1.start() ;
...
ct2 = new ConnectionTableNIO(..., false) ;
ct2.start() ;

Ports were not available because in the case of ConnectionTable, start() is called within the constructor, so that we were effectively calling it a second time. So removing the call to ct1.start() fixed that problem. 

On the other hand, for ConnectionTableNIO, because we pass a parameter false at the end of the signature, it means that start() is not called within the constructoir. So that particular invocation has to stay.

Even with these changes, we were still seewing the above exception when running the test testStopConnection(). I put in a very small 100 ms delay between each test, and thats eems to fix the problem. This probably needs further investigation to see why my test program works fine and always can reuse its port, whereas ConnectionTable seemingly cannot.
