But you never actually pass objects, you only ever pass references to objects. Making a parameter final means you can't change what object that parameter refers to. (you can still make changes to the object, if it's not immutable) Once you understand that its pretty clear what's happening.

I certainly got this problem with jsdk1.0 and 2.0, but it happens much earlier and more often in 2.0. The problem doesn't occur on Solaris or NT using the same JSDK (which is pure java). I found it occurred on about half the connections on 1.0, but normally after all the data had been sent to the client. With 2.0 it occurs much more often, often before significant amounts of data have been sent to the client. I suspect some sort of bug in JSDK that relies on some sort of automatic buffer flushing that doesn't occur on the linux JVM. I think I've tested under both the blackdown 1.1.7 and 1.2pre2. I don't think the problem exists under the IBM JVMs. I haven't tested extensively, but those are my observations. Let me know if you find a solution.

Correction: The problem occurs with 2.0 and more often with 2.1 (I got my versions confused). > What servlet engine are you using? Apache Jserv? The servlet engine that comes with the jsdk. It was primarily for testing and I haven't had enough linux/Apache experience to attempt the Jserv install.
