Emmanuel Lecharny commented on DIRMINA-1113:
--------------------------------------------
No, this is not the cause.
If I print what happens in the {{UnfairComparator.compare()}} method, the test
will fail if the second parameter is the preferred session.
{code:java}
@Override
public int compare(IoSession o1, IoSession o2) {
if (o1 == preferred) {
System.out.println( "O1 prefered" );
return -1;
}
if (o2 == preferred) {
System.out.println( "O2 prefered" );
return 1;
}
return 0;
}
{code}
generally prints :
{noformat}
O1 prefered
O1 prefered
{noformat}
and the test succeed, but when it prints :
{noformat}
O1 prefered
O1 prefered
O2 prefered
{noformat}
the test fails in this case. I have no idea why it happens (and it's quite
rare)...
