Injecting synthetic messages

[Matthew Phillips]

Hi all,

I have a timer thread inside a custom IoFilter that checks for  
request timeouts after sending a message. If a timeout occurs, it  
sends a synthetic message down the filter chain. The question is, is  
this thread safe, or am I violating the MINA thread model?

The following code is what I'm doing in the timer thread to inject  
the message:

  String filterName = ... // name of the timeout-checking filter

  NextFilter filter =
    session.getFilterChain ().getNextFilter (filterName);

  filter.messageReceived
    (session, new RequestTimeoutMessage ());

Any advice appreciated,

Cheers,

Matthew.
