Synchronization in messageReceived required?

Hi,

is it required to synchronize own method invocations from within the 
messageReceived method (IoHandlerAdaptor, DemuxingIoHandler) or are they 
already synced.

Best Regards
Michael

Hi Michael,

Please provide more details ? What do you mean with "own method invocations"
?
Please note that
a) mina will not call messageReceived concurrently for the same IoSession
b) IoHandler.messageReceived could be called concurrenlty for multiple
IoSessions
so if your accessing some shared state from within your messageReceived
implementation,
you need to provide proper synchronization.
