I've been looking in detail at the NIO changes and have a couple of questions. In section 3.7 we have the following:I think this is supposed to mean that there should be only one container thread doing actions related to a particular request processing, such as calling the read/write listeners, invoking async dispatches, etc. If that is correct, the statement could be more precise.
The Servlet container must access methods in ReadListener in a thread safe manner.
There is equivalent text in section 5.3:
The Servlet container must access methods in WriteListener in a thread safe manner.
I recall some discussions around this area but not this exact language. It is not clear to me how one accesses a method in a thread safe manner since thread safety is a property of the method implementation not of how it is accessed. A search of the archives did not provide any illumination either. So, I have two questions.
Q1. What exactly does the above mean?
Q2. Why was this requirement added?
