------- Additional Comments From [EMAIL PROTECTED]  2005-09-09 07:35 -------
Too much has said alread, but I also think it is not the only option to simply
synchronize.

Most of the time the different webapps/technologies do not utilize the same
content of such a session map. e.g. JSF and your home app mostly wont use the
same keys in this hashmap.
So why introduce a bottleneck? (and I didnt mean a real performance one, its
more  philosophical)
Why should one technique influence another one? And there is an impact, in the
worst case this synchronized map acts like a "sequencer".

What I would like to say is, its somehow reasonable to not simply synchronize,
but to find a hashmap which is able to handle this case.

This hashmap should be able to insert keys in concurrent. I one insert the same
key in parallel the result wont be deterministic, ok - fine.
And for sure, such a map should not lock (and not even wait for some "free me"
event) on get.

Isnt there a "cool" java collection developer here?
