Hello,
when debugging my server-side code - and only when debugging it - I receive
a ConcurrentModificationException during this method:
private void clean ()
{
Set<Map.Entry<String,Observator>> set = lst.entrySet();
Iterator<Map.Entry<String,Observator>> itr = set.iterator ();
while (itr.hasNext ())
{
Map.Entry<String,Observator> e = itr.next();
Observator o = e.getValue();
if (o.isOutdated())
itr.remove();
}
}
Note that this server-side code is called repeatedly by the client inside
as an RPC call a Timer.
When I run the application inside eclipse with Project -> Run As -> Web
Application (Super Dev Mode), no exception occurrs.
When I debug it inside eclipse with Project -> Debug As -> Web Application
(Super Dev Mode) *without any breakpoints*, no exception occurrs.
But when I debug while having breakpoints, the exception is thrown...
It seems to have something to do with stepping through server-side code
while the client is making RPC calls...
How do you deal with such problems?
Thanks
Magnus
