Bug ? Init is called twice in SingleThreadModel

Hal Lander Wed, 02 Jul 2003 12:45:51 -0700

The init method of my servlet is called twice if my class implements the SingleThreadModel. Full details are given below. If I remove "implements SingleThreadModel" init is called only once - as I would expect.

Is this a bug?
Any help would be appreciated.

Hal.

        {
                System.out.println("init called");
                return;
        }
}
