More info:
Took me some time to see, that you are using 1.4.5 as I think (maybe even
more recent, but definitely not the latest 1.5.2).
com.evermind.server.rmi.RmiServer has:
java.util.List eb;
<snatch>
public final void gb(ba ba1)
{
synchronized(eb)
{
eb.remove(ba1);
}
}
</snatch>
<snatch>
public RMIServer(ApplicationServer applicationserver)
{
..... blah blah blah .....
eb = new ArrayList();
..... blah blah blah .....
}
</snatch>
This is it... I don't however know what is the eb used for.
It looks ok (there is syncronized working with the list), however
something does not work right.
My guess: Move to 1.5.2 maybe?
