Remko Popma commented on LOG4J2-228:
------------------------------------
Imesh, thanks for the additional info. This is very helpful!
Ralph, the second event is 4 bytes shorter than the first event.
I believe the problem is in SerializedLayout, which does something special to
only write the header for the first event.
This works well for a (TCP) continuous stream where the recipient creates the
ObjectInputStream once and reuses that stream for all events, but in Imesh's
case (with DatagramPackets) he creates a new ObjectInputStream for every event,
so the new ObjectInputStream expects a header again.
Perhaps the appender should tell SerializedLayout whether to include the header
every time or only once?
